We investigate the performance of a source location method that combines multichannel semblance and particle motions and is being increasingly used to obtain estimates of the source locations of very long period (VLP) seismic signals recorded on volcanoes. The method makes use of the radial particle motions and large wavelengths that characterize the VLP events. To assess the capabilities of this radial semblance method, and to better understand its limitations, we quantify the effects of window length, noise contents of the signal, inaccurate velocity models, receiver coverage, and orientation errors in the horizontal components of the receivers. Our results show that the semblance method performs best when (1) the noise level is low enough to allow a good characterization of the waveforms, (2) the sources are located at distances between one half of the average receiver spacing and about two times the network aperture, and (3) the orientations of the horizontal components of the seismometers are known with relative accuracy. When these requirements are met, the radial semblance method constitutes an adequate tool to obtain preliminary locations of VLP volcanic signals recorded by broadband networks. Moreover, we provide a formula to determine the radial semblance level that should be used to define error regions associated to the estimated source locations.

Fire has been viewed as detrimental to caribou because it destroys the slow-growing climax forage lichens that caribou utilize in winter. Other researchers argued that caribou were not reliant on lichens and that fire may be beneficial, even in the short term. We evaluated the distribution of caribou relative to recent fires (<50 years old) within the current winter range of the Nelchina caribou herd in east-central Alaska. To address issues concerning independence and spatial and temporal scales, we used both conventional very high frequency and global positioning system telemetry to estimate caribou use relative to recent, known-aged burns. In addition, we used two methods to estimate availability of different habitat classes. Caribou used recently burned areas much less than expected, regardless of methodologies used. Moreover, within burns, caribou were more likely to use habitat within 500 m of the burn perimeter than core areas. Methods for determining use and availability did not have large influences on our measures of habitat selectivity.

Recent research has documented that Pacific salmon carcasses serve as a key delivery vector of marine-derived nutrients into the freshwater portions of their ecosystems. This nutrient supply plays a critical biological feedback role in salmon sustainability by supporting juvenile salmon production. We first demonstrate how nutrient feedback potential to juvenile production may be unaccounted for in spawner-recruit models of populations under long-term exploitation. We then present a heuristic, life history-based, spreadsheet survival model that incorporates salmon carcass-driven nutrient feedback to the freshwater components of the salmon ecosystem. The productivity of a hypothetical coho salmon population was simulated using rates from the literature for survival from spawner to egg, egg to fry, fry to smolt, and smolt to adult. The effects of climate variation and nutrient feedback on survival were incorporated, as were density-dependent effects of the numbers of spawners and fry on freshwater survival of eggs and juveniles. The unexploited equilibrium population was subjected to 100 years of 20, 40, 60, and 80% harvest. Each harvest scenario greater than 20% brought the population to a reduced steady state, regardless of generous compensatory survival at low population sizes. Increasing harvest reduced the positive effects of nutrient contributions to population growth. Salmon researchers should further explore this modeling approach for establishing escapement goals. Given the importance of nutrient feedback, managers should strive for generous escapements that support nutrient rebuilding, as well as egg deposition, to ensure strong future salmon production.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"American Fisheries Society Symposium","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","issn":"08922284","usgsCitation":"Knudsen, E., Symmes, E., and Margraf, F., 2003, Searching for a life history approach to salmon escapement management: American Fisheries Society Symposium, v. 2003, no. 34, p. 261-276.","startPage":"261","endPage":"276","numberOfPages":"16","costCenters":[],"links":[{"id":235733,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"2003","issue":"34","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505b8853e4b08c986b3168f7","contributors":{"authors":[{"text":"Knudsen, E.E.","contributorId":26116,"corporation":false,"usgs":true,"family":"Knudsen","given":"E.E.","email":"","affiliations":[],"preferred":false,"id":404486,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Symmes, E.W.","contributorId":45095,"corporation":false,"usgs":true,"family":"Symmes","given":"E.W.","email":"","affiliations":[],"preferred":false,"id":404487,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Margraf, F.J.","contributorId":47738,"corporation":false,"usgs":true,"family":"Margraf","given":"F.J.","email":"","affiliations":[],"preferred":false,"id":404488,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}} ,{"id":70025260,"text":"70025260 - 2003 - Post-breeding distribution of Long-tailed Ducks Clangula hyemalis from the Yukon-Kuskokwim Delta, Alaska","interactions":[],"lastModifiedDate":"2022-08-16T15:08:59.701556","indexId":"70025260","displayToPublicDate":"2003-01-01T00:00:00","publicationYear":"2003","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":3764,"text":"Wildfowl","onlineIssn":"2052-6458","printIssn":"0954-6324","active":true,"publicationSubtype":{"id":10}},"title":"Post-breeding distribution of Long-tailed Ducks Clangula hyemalis from the Yukon-Kuskokwim Delta, Alaska","docAbstract":"Breeding populations of Long-tailed Ducks Clangula hyemalis have declined in western Alaska, particularly on the Yukon-Kuskokwim (Y-K) Delta, and the species is currently considered a species of particular concern by the U.S. Fish & Wildlife Service in Alaska. Potential factors that may have contributed to this decline that occurred away from the breeding grounds could not be considered since moulting and wintering areas for this population were unknown. A study was conducted in 1998 and 1999 to locate the moulting and wintering areas of the Y-K Delta breeding population. VHF and satellite transmitters were deployed to identify areas used by moulting birds. Based on the locations identified by satellite telemetry, aerial surveys were flown to locate birds marked with VHF transmitters, then low-level aerial surveys were designed and conducted to determine the number of birds using these and adjacent areas. Moulting locations of 54 marked female Long-tailed Ducks were identified: 13 marked females were found in wetlands and large lakes on the Y-K Delta, 11 in coastal lagoons at St Lawrence Island, Alaska, and two along the coast of the Chukotka Peninsula, Russia. A autumn staging area was identified along the east coast of the Chukotka Peninsula which was used by seven of 10 birds with satellite transmitters providing locations during that period. Birds wintered in coastal waters of the North Pacific Ocean north of 50°N and between 150°E and 130°W. The wide distribution of birds in winter suggests little probability of a single factor in winter contributing to the decline.

The earthquake created zones of ground cracks from 0.1 to 2.8 km long along at least five northwest- to north-northwest-striking faults in the epicentral area. Individual cracks had extensional openings generally from 1 to 10 mm wide. No cracks displayed obvious vertical separation, and only one zone showed permissive evidence of right-lateral separation. Over the 8 days following the mainshock (the period over which the cracks were found), aftershocks formed a dominant northeast trend suggesting the earthquake occurred along a northeast-striking structure. However, no ground breakage was found along faults striking parallel to this northeast aftershock alignment, and subsequent aftershocks formed a conjugate northwest trend. Based on the location and character of the five zones, the observed cracks are attributed to secondary fault slip and shaking effects. The earthquake also created ground cracks along at least two faults 15-25 km from the epicenter. In both of these cases, the faults had documented histories of prior ground cracking, indicating that they are particularly susceptible to such triggered deformation.

Computational results illustrate the profound effects of pore-pressure diffusivities on debris-flow surge depths and velocities. ?? 2003 Millpress,.","largerWorkTitle":"International Conference on Debris-Flow Hazards Mitigation: Mechanics, Prediction, and Assessment, Proceedings","conferenceTitle":"3rd International Conference on Debris-Flow Hazards Mitigation: Mechanics, Prediction, and Assessment","conferenceDate":"10 September 2003 through 12 September 2003","conferenceLocation":"Davos","language":"English","usgsCitation":"Savage, S., and Iverson, R., 2003, Surge dynamics coupled to pore-pressure evolution in debris flows, in International Conference on Debris-Flow Hazards Mitigation: Mechanics, Prediction, and Assessment, Proceedings, v. 1, Davos, 10 September 2003 through 12 September 2003, p. 503-514.","startPage":"503","endPage":"514","numberOfPages":"12","costCenters":[],"links":[{"id":235818,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505ba279e4b08c986b31f72a","contributors":{"editors":[{"text":"Rickenmann D.Chen C.L.","contributorId":128322,"corporation":true,"usgs":false,"organization":"Rickenmann D.Chen C.L.","id":536561,"contributorType":{"id":2,"text":"Editors"},"rank":1}],"authors":[{"text":"Savage, S.B.","contributorId":99751,"corporation":false,"usgs":true,"family":"Savage","given":"S.B.","email":"","affiliations":[],"preferred":false,"id":404960,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Iverson, R.M. 0000-0002-7369-3819","orcid":"https://orcid.org/0000-0002-7369-3819","contributorId":16435,"corporation":false,"usgs":true,"family":"Iverson","given":"R.M.","affiliations":[],"preferred":false,"id":404959,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}} ,{"id":70025149,"text":"70025149 - 2003 - Subcellular compartmentalization of Cd and Zn in two bivalves.

Results show that the partitioning of metals to organelles, Œenzymes¹ and metallothioneins (MT) comprise a subcellular compartment containing trophically available metal (TAM; i.e. metal trophically available to predators), and that because this partitioning varies with species, animal size and metal, TAM is similarly influenced. Clams from San Francisco Bay, California, were exposed for 14 d to 3.5 µg l-1 Cd and 20.5 µg l-1 Zn, including 109Cd and 65Zn as radiotracers, and were used in feeding experiments with grass shrimp Palaemon macrodatylus, or used to investigate the subcellular partitioning of metal. Grass shrimp fed Cd-contaminated P. amurensis absorbed ~60% of ingested Cd, which was in accordance with the partitioning of Cd to the bivalve¹s TAM compartment (i.e. Cd associated with organelles, Œenzymes¹ and MT); a similar relationship was found in previous studies with grass shrimp fed Cd-contaminated oligochaetes. Thus, TAM may be used as a tool to predict the trophic transfer of at least Cd. Subcellular fractionation revealed that ~34% of both the Cd and Zn accumulated by M. balthica was associated with TAM, while partitioning to TAM in P. amurensis was metal-dependent (~60% for TAM-Cd%, ~73% for TAM-Zn%). The greater TAM-Cd% of P. amurensis than M. balthica is due to preferential binding of Cd to MT and Œenzymes¹, while enhanced TAM-Zn% of P. amurensis results from a greater binding of Zn to organelles. TAM for most species-metal combinations was size-dependent, decreasing with increased clam size. Based on field data, it is estimated that of the 2 bivalves, P. amurensis poses the greater threat of Cd exposure to predators because of higher tissue concentrations and greater partitioning as TAM; exposure of Zn to predators would be similar between these species.

The spectral library is used to automate the processing of hyperspectral imagery for potential real-time material identification and mapping. Field based spectra were compared to the airborne imagery using the database to identify and map two species of SAV (Myriophyllum spicatum and Vallisneria americana). Overall accuracy of the vegetation maps derived from hyperspectral imagery was determined by comparison to a product that combined aerial photography and field based sampling at the end of the SAV growing season.

They suggest that because the iron isotope fractionation observed in their experiments spans virtually the entire range observed in sedimentary rocks, Fe(II)–Fe(III) aqueous speciation may play a major role in determining iron isotope variations in nature where Fe(II) and Fe(III) can become physically separated. They discounted earlier conclusions by us and others [2] ; [3] that significant equilibrium fractionation between specific coexisting Fe(II)- or Fe(III)-aqueous complexes (e.g., between aqueous Fe(II)(OH)x(aq)and Fe(II)(aq) ion) is capable of producing iron isotope contrasts that can be preserved in nature. This is an important contribution not only because the authors recognize the importance of abiotic equilibrium iron isotope fractionation in nature in contrast to previous assertions [4], but also because it will help to focus discussion on the development and evaluation of experimental approaches that can reveal abiotic fractionation mechanisms. However, in this Comment we propose that the experiments presented in this paper cannot be interpreted as straightforwardly as Johnson et al. contend. In particular, we show that in one of their critical experiments attainment of either isotope mass balance or equilibrium was not demonstrated, and thus the results of that experiment cannot be used to calculate an Fe(II)–Fe(III) equilibrium fractionation factor.

We examine tectonic aspects of foreland evolution as part of a broader study of why some forelands are rich in MVT deposits, whereas others are barren. The type of orogenic foreland (collisional versus Andean-type versus inversion-type) is not a first-order control, because each has MVT deposits (e.g., Northern Arkansas, Pine Point, and Cevennes, respectively). In some MVT districts (e.g., Tri-State and Central Tennessee), mineralization took place atop an orogenic forebulge, a low-amplitude (a few hundred meters), long-wavelength (100-200 km) swell formed by vertical loading of the foreland plate. In the foreland of the active Banda Arc collision zone, a discontinuous forebulge reveals some of the physiographic and geologic complexities of the forebulge environment, and the importance of sea level in determining whether or not a forebulge will emerge and thus be subject to erosion. In addition to those on extant forebulges, some MVT deposits occur immediately below unconformities that originated at a forebulge, only to be subsequently carried toward the orogen by the plate-tectonic conveyor (e.g., Daniel's Harbour and East Tennessee). Likewise, some deposits are located along syn-collisional, flexure-induced normal and strike-slip faults in collisional forelands (e.g., Northern Arkansas, Daniel's Harbour, and Tri-State districts). These findings reveal the importance of lithospheric flexure, and suggest a conceptual tectonic model that accounts for an important subset of MVT deposits-those in the forelands of collisional orogens. The MVT deposits occur both in flat-lying and in thrust-faulted strata; in the latter group, mineralization postdated thrusting in some instances (e.g., Picos de Europa) but may have predated thrusting in other cases (e.g., East Tennessee).","largerWorkTitle":"","language":"English","publisher":"Springer","doi":"10.1007/s00126-003-0355-2","issn":"","usgsCitation":"Bradley, D.C., and Leach, D.L., 2003, Tectonic controls of Mississippi Valley-type lead-zinc mineralization in orogenic forelands: Mineralium Deposita, v. 38, no. 6, p. 652-667, https://doi.org/10.1007/s00126-003-0355-2.","productDescription":"16 p.","startPage":"652","endPage":"667","numberOfPages":"16","costCenters":[{"id":318,"text":"Geosciences and Environmental Change Science Center","active":true,"usgs":true}],"links":[{"id":236179,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"38","issue":"6","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505ba456e4b08c986b320275","contributors":{"authors":[{"text":"Bradley, D.

Bear Creek, located in northwest Alabama and northeast Mississippi, has seen changes to its fauna, possibly the result of impoundment, channelization, wastewater discharge, and sedimentation from such sources such as strip mining, agriculture, and silviculture. The most obvious influences have been impoundment of the lowermost 32 km of Bear Creek by Pickwick Reservoir of Tennessee River, the construction of four dams within the system, construction of a 29-km-long channel designed to limit flooding, and bank destabilization. Mussels are absent from much of the system and faunal composition has apparently been altered where mussels persist, based on comparison to limited previous studies. The most notable changes are the loss of Cumberlandian species diversity and the apparent increase in Ohioan species diversity. We sampled 40 stations in the Bear Creek system and report 32 mussel species live or fresh dead, including 3 Cumberlandian species, and 2 others weathered dead. Fourteen of these species were not reported in two earlier studies. During this study the most depauperate populations were upstream of Bear Creek km 41.0 and in tributaries. No mussels were collected immediately downstream of dams, and diversity gradually increased downstream from the lowermost main channel dam until 28 species occurred together in a free-flowing reach shortly before entering Pickwick Reservoir. One weathered dead zebra mussel, Dreisenna polymorpha, was also collected, representing a new tributary record. The population of Epioblasma brevidens in Bear Creek is the only population of that species known in the lower Tennessee River system, and the population of Lexingtonia dolabelloides, another new tributary record, is one of only two populations of that species known downstream of Paint Rock River.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"American Malacological Bulletin","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","issn":"07402783","usgsCitation":"McGregor, S., and Garner, J., 2003, Changes in the freshwater mussel (Bivalvia: Unionidae) fauna of the Bear Creek system of Northwest Alabama and Northeast Mississippi: American Malacological Bulletin, v. 18, no. 1-2, p. 61-70.","startPage":"61","endPage":"70","numberOfPages":"10","costCenters":[],"links":[{"id":235783,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"18","issue":"1-2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059f431e4b0c8380cd4bbc7","contributors":{"authors":[{"text":"McGregor, S.W.","contributorId":93659,"corporation":false,"usgs":true,"family":"McGregor","given":"S.W.","email":"","affiliations":[],"preferred":false,"id":404958,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Garner, J.T.","contributorId":10209,"corporation":false,"usgs":true,"family":"Garner","given":"J.T.","email":"","affiliations":[],"preferred":false,"id":404957,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}} ,{"id":70025268,"text":"70025268 - 2003 - Cassini-VIMS at Jupiter: Solar occultation measurements using Io","interactions":[],"lastModifiedDate":"2012-03-12T17:20:28","indexId":"70025268","displayToPublicDate":"2003-01-01T00:00:00","publicationYear":"2003","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":1963,"text":"Icarus","active":true,"publicationSubtype":{"id":10}},"title":"Cassini-VIMS at Jupiter: Solar occultation measurements using Io","docAbstract":"We report unusual and somewhat unexpected observations of the jovian satellite Io, showing strong methane absorption bands. These observations were made by the Cassini VIMS experiment during the Jupiter flyby of December/January 2000/2001. The explanation is straightforward: Entering or exiting from Jupiter's shadow during an eclipse, Io is illuminated by solar light which has transited the atmosphere of Jupiter. This light, therefore becomes imprinted with the spectral signature of Jupiter's upper atmosphere, which includes strong atmospheric methane absorption bands. Intercepting solar light refracted by the jovian atmosphere, Io essentially becomes a \"miffor\" for solar occultation events of Jupiter. The thickness of the layer where refracted solar light is observed is so large (more than 3000 km at Io's orbit), that we can foresee a nearly continuous multi-year period of similar events at Saturn, utilizing the large and bright ring system. During Cassini's 4-year nominal mission, this probing tecnique should reveal information of Saturn's atmosphere over a large range of southern latitudes and times. ?? 2003 Elsevier Inc.

Seventeen mature migrant eels (870-1,240 mm; 2,000-6,380 g) were implanted with coded acoustic transmitters and released. Their movements in the reservoir were monitored for 14 months with stationary data logging and manual tracking receivers. The downstream migration of sexually maturing eels was found to occur mainly at night, usually during, or immediately after, rainfall events. Eels tended to travel at the surface, within the upper 4 m of the water column, at speeds ranging from 16 to 89 cm/s. Upon reaching the headrace, eels typically spent time searching, presumably for an unobstructed downstream route. In order to aid downstream passage of eels at the Patea Dam, power station operators began spillway opening trials during peak migration periods. Although this allowed some migrant eels to safely pass over the dam, information on the relative effectiveness and cost of this method over other possible mitigation methods is still required. ??

The ideal structural formulas for sI and sII are, respectively, S2L6 ?? 46H2O and S16L???8 ?? 136H2O, where S denotes a polyhedral cage with 20 vertices, L a 24-cage, and L??? a 28-cage. The space-filling polyhedral cages are defined by the oxygen atoms of the hydrogen-bonded network of water molecules. Collectively, the mean cage volume ratio is 1.91 : 1.43 : 1 for the 28-cage : 24-cage : 20-cage, which correspond to equivalent sphere radii of 4.18, 3.79, and 3.37 A??, respectively. At 100 K, mean polyhedral volumes are 303.8, 227.8, and 158.8 A??3 for the 28-cage, 24-cage, and 20-cage, respectively. In general, the 20-cage volume for a sII is larger than that of a sI, although trimethylene oxide is an exception. The temperature dependence of the cage volumes reveals differences between apparently similar cages with similar occupants. In the case of trimethylene oxide hydrate, which forms both sI and sII, the 20-cages common to both structures contract quite differently. From 220 K, the sII 20-cage exhibits a smooth monotonic reduction in size, whereas the sI 20-cage initially expands upon cooling to 160 K, then contracts more rapidly to 10 K, and overall the sI 20-cage is larger than the sII 20-cage. The volumes of the large cages in both structures contract monotonically with decreasing temperature. These differences reflect reoriented motion of the trimethyelene oxide molecule in the 24-cage of sI, consistent with previous spectroscopic and calorimetric studies. For the 20-cages in methane hydrate (sI) and a mixed methane-ethane hydrate (sII), both containing methane as the guest molecule, the temperature dependence of the 20-cage volume in sII is much less than that in sI, but sII is overall larger in volume.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Canadian Journal of Physics","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","doi":"10.1139/p02-141","issn":"00084204","usgsCitation":"Chakoumakos, B., Rawn, C., Rondinone, A., Stern, L., Circone, S., Kirby, S.H., Ishii, Y., Jones, C., and Toby, B., 2003, Temperature dependence of polyhedral cage volumes in clathrate hydrates: Canadian Journal of Physics, v. 81, no. 1-2, p. 183-189, https://doi.org/10.1139/p02-141.","startPage":"183","endPage":"189","numberOfPages":"7","costCenters":[],"links":[{"id":234394,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":208570,"rank":9999,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1139/p02-141"}],"volume":"81","issue":"1-2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505ba4c2e4b08c986b320576","contributors":{"authors":[{"text":"Chakoumakos, B.C.","contributorId":32338,"corporation":false,"usgs":true,"family":"Chakoumakos","given":"B.C.","email":"","affiliations":[],"preferred":false,"id":408664,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Rawn, C.J.","contributorId":70574,"corporation":false,"usgs":true,"family":"Rawn","given":"C.J.","email":"","affiliations":[],"preferred":false,"id":408670,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Rondinone, A.J.","contributorId":34695,"corporation":false,"usgs":true,"family":"Rondinone","given":"A.J.","email":"","affiliations":[],"preferred":false,"id":408665,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Stern, L.A.","contributorId":38293,"corporation":false,"usgs":true,"family":"Stern","given":"L.A.","email":"","affiliations":[],"preferred":false,"id":408667,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Circone, S.","contributorId":35901,"corporation":false,"usgs":true,"family":"Circone","given":"S.","email":"","affiliations":[],"preferred":false,"id":408666,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Kirby, S.

Deposits range from imbricate gravel and granules indicating flow locally extending up the Yukon valley, to more distal sediments consisting of at least 10 couplets of planar sands, granules, and climbing ripples with up-valley paleocurrent indicators overlain by massive silt. An interglacial organic silt, occurring within the sequence, indicates at least two flood events are associated with an earlier glaciation, and at least three flood events are associated with a later glaciation which postdates the organic silt. A minimum age for the floods is provided by a glass fission track age of 560,000 ?? 80,000 yr on the GI tephra, which occurs 8 m above the flood beds. A maximum age of 780,000 yr for the floods is based on normal magnetic polarity of the sediments. These age constraints allow us to correlate the flood events to the early-middle Pleistocene. And further, the outburst floods indicate extensive glaciation of the Yukon-Tanana Upland during the early-middle Pleistocene, likely representing the most extensive Pleistocene glaciation of the area. ?? 2003 University of Washington.

It is the variability of these hydrologic processes that produces variable patterns of nutrient transport in both space and time. In this paper, we explore how hydrologic “connectivity” potentially affects nutrient transport. Hydrologic connectivity is defined as the condition by which disparate regions on the hillslope are linked via subsurface water flow. We present simulations that suggest that for much of the year, water draining through a catchment is spatially isolated. Only rarely, during storm and snowmelt events when antecedent soil moisture is high, do our simulations suggest that mid-slope saturation (or near saturation) occurs and that a catchment connects from ridge to valley. Observations during snowmelt at a small headwater catchment in Idaho are consistent with these model simulations. During early season discharge episodes, in which the mid-slope soil column is not saturated, the electrical conductivity in the stream remains low, reflecting a restricted, local (lower slope) source of stream water and the continued isolation of upper and mid-slope soil water and nutrients from the stream system. Increased streamflow and higher stream water electrical conductivity, presumably reflecting the release of water from the upper reaches of the catchment, are simultaneously observed when the mid-slope becomes sufficiently wet. This study provides preliminary evidence that the seasonal timing of hydrologic connectivity may affect a range of ecological processes, including downslope nutrient transport, C/N cycling, and biological productivity along the toposequence. A better elucidation of hydrologic connectivity will be necessary for understanding local processes as well as material export from land to water at regional and global scales.

This paradox of seabird biogeography is explained by the Anadyr “Green Belt” - a current that advects nutrients and plankton over 1200 km from the outer Bering Sea shelf-edge to the central Chukchi Sea. Turbulent upwelling of this nutrient-rich water at Anadyr and Bering straits further enhances high levels of primary production (360 gC m-2y-1) and helps sustain the enormous biomass of zooplankton entrained in the Anadyr Current. Primary production in adjacent waters of the Chukchi Sea (420 gC m-2y-1) exceeds that observed below Bering Strait, and zooplankton are equally abundant. Auklets account for 49% of total food consumption below Bering Strait (411 mt d-1), whereas piscivores dominate (88% of 179 mt d-1) in the Chukchi Sea. Of 2 million seabirds in the Chukchi region, auklets (6%) are supplanted by planktivorous phalaropes (25%), and piscivorous murres (38%) and kittiwakes (15%). Average carbon flux to seabirds (0.65 mgC m-2d-1) over the whole region is more typical of upwelling than shelf ecosystems. The pelagic distribution of seabirds in the region appears to be a function of advection, productivity and water column stability. Planktivores flourish in areas with high zooplankton concentrations on the edge of productive upwelling and frontal zones along the “Green Belt”, whereas piscivores avoid turbulent, mixed waters and forage in stable, stratified waters along the coast and in the central Chukchi Sea.
