We developed a bioeconomic computer model that included links between population density and growth, recruitment, and fishing effort for this fishery. Random variability was included in the stock–recruitment relation and in a simulated population assessment. We used the model in an adaptive management framework to evaluate the effects of the rehabilitation plan on both commercial and sport fisheries and to search for ways to improve the plan. Results indicate that the current quota policy is a member of a set of policies that would meet most management goals and increase total value of the fishery. Sensitivity analyses indicate that this conclusion is robust over a wide range of biological conditions. We predict that commercial fishers will lose money relative to the baseline condition, but they may receive other benefits from the elimination of the common‐property nature of the fishery. The prospect exists for managing variability in harvest and stock size and for maximizing economic returns in the fishery, but more information is required, primarily on sportfishing effort dynamics and angler preferences. Stock‐recruitment relations, density dependence of growth, and dynamics of sportfishing effort are the primary sources of uncertainty limiting the precision of our predictions. The current quota policy is about as good as other policies at reducing this uncertainty and appears, overall, to be one of the best choices for this fishery. The analytical techniques used in this study were primarily simple, heuristic approaches that could be easily transferred to other studies.</span></p>","language":"English","publisher":"Oxford Academic","doi":"10.1577/1548-8675(1992)012<0703:EFRUUA>2.3.CO;2","usgsCitation":"Johnson, B., Milliman, S., Bishop, R., and Kitchell, J., 1992, Evaluating fishery rehabilitation under uncertainty: A bioeconomic analysis of quota management for the Green Bay yellow perch fishery: North American Journal of Fisheries Management, v. 12, no. 4, p. 703-720, https://doi.org/10.1577/1548-8675(1992)012<0703:EFRUUA>2.3.CO;2.","productDescription":"18 p.","startPage":"703","endPage":"720","costCenters":[{"id":606,"text":"Upper Midwest Environmental Sciences Center","active":true,"usgs":true}],"links":[{"id":134350,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Wisconsin","city":"Green Bay","otherGeospatial":"Lake Michigan","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -88.03861528382518,\n              44.5806619990727\n            ],\n            [\n              -88.03861528382518,\n              44.52036667216541\n            ],\n            [\n              -87.93610890800826,\n              44.52036667216541\n            ],\n            [\n              -87.93610890800826,\n              44.5806619990727\n            ],\n            [\n              -88.03861528382518,\n              44.5806619990727\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"12","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a09e4b07f02db5fb08a","contributors":{"authors":[{"text":"Johnson, Barry L.","contributorId":95009,"corporation":false,"usgs":true,"family":"Johnson","given":"Barry L.","affiliations":[],"preferred":false,"id":312806,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Milliman, S.R.","contributorId":100809,"corporation":false,"usgs":true,"family":"Milliman","given":"S.R.","email":"","affiliations":[],"preferred":false,"id":312807,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Bishop, R.C.","contributorId":79439,"corporation":false,"usgs":true,"family":"Bishop","given":"R.C.","email":"","affiliations":[],"preferred":false,"id":312805,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Kitchell, J.F.","contributorId":33259,"corporation":false,"usgs":true,"family":"Kitchell","given":"J.F.","email":"","affiliations":[],"preferred":false,"id":312804,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

The strongly varying bathymetry and coastline geometry of the harbor generate complex spatial patterns in the modeled tidal currents which are verified by shipboard acoustic Doppler surveys. Lagrangian exchange experiments demonstrate that tidal currents rapidly exchange and mix material near the inlets of the harbor due to asymmetry in the ebb/flood response. This tidal mixing zone extends roughly a tidal excursion from the inlets and plays an important role in the overall flushing of the harbor. Because the tides can only efficiently mix material in this limited region, however, harbor flushing must be considered a two step process: rapid exchange in the tidal mixing zone, followed by flushing of the tidal mixing zone by nontidal residual currents. Estimates of embayment flushing based on tidal calculations alone therefore can significantly overestimate the flushing time that would be expected under typical environmental conditions. Particle-release simulations from point sources also demonstrate that while the tides efficiently exchange material in the vicinity of the inlets, the exact nature of dispersion from point sources is extremely sensitive to the timing and location of the release, and the distribution of particles is streaky and patchlike. This suggests that high-resolution modeling of dispersion from point sources in these regions must be performed explicitly and cannot be parameterized as a plume with Gaussian-spreading in a larger scale flow field.</span></p>","language":"English","publisher":"American Geophysical Union","publisherLocation":"Richmond, VA","doi":"10.1029/92JC01429","usgsCitation":"Signell, R.P., and Butman, B., 1992, Modeling tidal exchange and dispersion in Boston Harbor: Journal of Geophysical Research C: Oceans, v. 97, no.

Collectively, these observations are inconsistent with the Milankovitch hypothesis for the origin of the Pleistocene glacial cycles but they are consistent with the thesis that these cycles originated from internal nonlinear feedbacks within the atmosphere-ice sheet-ocean system.</span></p>","language":"English","publisher":"American Association for the Advancement of Science","doi":"10.1126/science.258.5080.255","issn":"00368075","usgsCitation":"Winograd, I., Coplen, T., Landwehr, J., Riggs, A., Ludwig, K.R., Szabo, B.J., Kolesar, P.T., and Revesz, K., 1992, Continuous 500,000-year climate record from vein calcite in Devils Hole, Nevada: Science, v. 258, no. 5080, p. 255-260, https://doi.org/10.1126/science.258.5080.255.","productDescription":"6 p.","startPage":"255","endPage":"260","costCenters":[],"links":[{"id":224862,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Nevada","otherGeospatial":"Devils Hole","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -116.39119726931067,\n              36.492297411172274\n            ],\n            [\n              -116.39119726931067,\n              36.35139920027308\n            ],\n            [\n              -116.22830272843797,\n              36.35139920027308\n            ],\n            [\n              -116.22830272843797,\n              36.492297411172274\n            ],\n            [\n              -116.39119726931067,\n              36.492297411172274\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"258","issue":"5080","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5059fa56e4b0c8380cd4da62","contributors":{"authors":[{"text":"Winograd, I.J.","contributorId":10408,"corporation":false,"usgs":true,"family":"Winograd","given":"I.J.","affiliations":[],"preferred":false,"id":375033,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Coplen, T.B.","contributorId":34147,"corporation":false,"usgs":true,"family":"Coplen","given":"T.B.","affiliations":[],"preferred":false,"id":375035,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Landwehr, J.M.","contributorId":39815,"corporation":false,"usgs":true,"family":"Landwehr","given":"J.M.","email":"","affiliations":[],"preferred":false,"id":375036,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Riggs, A.C.","contributorId":41462,"corporation":false,"usgs":true,"family":"Riggs","given":"A.C.","email":"","affiliations":[],"preferred":false,"id":375037,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Ludwig, Kenneth R.","contributorId":63417,"corporation":false,"usgs":true,"family":"Ludwig","given":"Kenneth","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":375039,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Szabo, Barney J.","contributorId":6848,"corporation":false,"usgs":true,"family":"Szabo","given":"Barney","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":375032,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Kolesar, Peter T.","contributorId":32296,"corporation":false,"usgs":true,"family":"Kolesar","given":"Peter","email":"","middleInitial":"T.","affiliations":[],"preferred":false,"id":375034,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Revesz, K.M.","contributorId":78787,"corporation":false,"usgs":true,"family":"Revesz","given":"K.M.","email":"","affiliations":[],"preferred":false,"id":375038,"contributorType":{"id":1,"text":"Authors"},"rank":8}]}}

The results of experiments on the calcite to aragonite transformation in polycrystalline marble are different from those for earlier experiments on powdered and single-crystal calcite. The transformation in the polycrystalline samples occurs by different mechanisms, with a different temperature dependence, and at a markedly slower rate. This work demonstrates the importance of kinetic studies on fully dense polycrystalline aggregates for understanding mineralogic phase changes in nature. Extrapolation of these results to geological time scales suggests that transformation of calcite to aragonite does not occur in the absence of volatiles at temperatures below 200°C. Kinetic hindrance is likely to extend to higher temperatures in more complex transformations.</span></p>","language":"English","publisher":"American Association for the Advancement of Science","doi":"10.1126/science.258.5079.110","issn":"00368075","usgsCitation":"Hacker, B.R., Kirby, S.H., and Bohlen, S., 1992, Time and metamorphic petrology: Calcite to aragonite experiments: Science, v. 258, no. 5079, p. 110-112, https://doi.org/10.1126/science.258.5079.110.","productDescription":"3 p.","startPage":"110","endPage":"112","costCenters":[],"links":[{"id":224909,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"258","issue":"5079","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bb391e4b08c986b325e85","contributors":{"authors":[{"text":"Hacker, B.

Aerial surveys of elk (<i>Cervus elaphus</i>) in northcentral Idaho illustrate that differential visibility of age or sex classes can produce biased ratio estimates. Visibility models may be used to provide corrected estimates of ratios and their variability that incorporates errors due to sampling, visibility bias, and visibility estimation.</p>","language":"English","publisher":"Wiley","doi":"10.2307/3809465","usgsCitation":"Samuel, M., Steinhorst, R., Garton, E.O., and Unsworth, J.W., 1992, Estimation of wildlife population

Hypocentral depths and the dips of rupture zones (preferred nodal planes) are among the seismological variables most likely associated with geologic structure in the stable continental region (SCR) of central and eastern North America (CENA). We compiled well-constrained depths and dips for 20 SCR shocks in CENA with magnitudes&nbsp;</span><strong>(M)</strong><span>&nbsp;between 4.9 and 6.8. The appendix lists the values we chose, our reasons for selecting specific values, and the uncertainties associated with each value. The median depth is 10 km, but an aseismic interval from about 15 to 25 km depth separates three midcrustal hypocenters from the others. The median dip of preferred nodal planes is 54°, and the larger earthquakes tend to rupture along shallower dips.</span></p><p><span>These results combined with geologic evidence lead to four inferences about SCR earthquakes with&nbsp;<strong>M</strong>≥ 4.9 in CENA. (1) If rupture generally progresses updip, then the tendency for large earthquakes to rupture more shallowly-dipping surfaces than small earthquakes can explain the scarcity of surface ruptures in CENA. (2) The few midcrustal earthquakes might be evidence that mafic or granulite facies rocks are present. (3) CENA seismicity is concentrated in Late Proterozoic and Phanerozoic orogens and extended terranes that rim an older, stable, central craton. Unusually shallow large CENA earthquakes have been observed only in the central craton, where they might cause severe but localized shaking. (4) Earthquakes in the Appalachian orogen tend to be shallower than those of comparable size in the Late Proterozoic rifted continental margin that underlies and borders the northwest side of the orogen. As a result, some Appalachian earthquakes could cause more localized shaking than comparable shocks in the rifted margin.</span></p>","language":"English","publisher":"GeoScienceWorld","doi":"10.1785/gssrl.63.4.491","issn":"08950695","usgsCitation":"Wheeler, R.L., and Johnston, A.C., 1992, Geologic implications of earthquake source parameters in central and eastern North America: Seismological Research Letters, v. 63, no. 4, p. 491-514, https://doi.org/10.1785/gssrl.63.4.491.","productDescription":"24 p.","startPage":"491","endPage":"514","costCenters":[],"links":[{"id":224560,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"Canada, United States","otherGeospatial":"eastern North America","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -98.87845690846513,\n              27.2189375296481\n            ],\n            [\n              -80.70241480266644,\n              24.59677320228481\n            ],\n            [\n              -76.37941551202118,\n              29.294020120121743\n            ],\n            [\n              -58.98394270839073,\n              46.79924420551643\n            ],\n            [\n              -63.54301504122161,\n              48.16421851147584\n            ],\n            [\n              -72.09338175945517,\n              45.50996289514734\n            ],\n            [\n              -81.4973905072629,\n              38.74095872321604\n            ],\n            [\n              -99.05270220712828,\n              31.694486578592894\n            ],\n            [\n              -98.87845690846513,\n              27.2189375296481\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","volume":"63","issue":"4","noUsgsAuthors":false,"publicationDate":"1992-10-01","publicationStatus":"PW","scienceBaseUri":"505a1981e4b0c8380cd559f8","contributors":{"authors":[{"text":"Wheeler, R.

Our purpose was threefold: (1) to simulate nitrate retention in response to change in load in a third-order stream, (2) to differentiate biotic versus hydrologie factors in nitrate retention, and (3) to produce a research tool whose properties are consistent with laboratory and field observations. Hydrodynamic parameters were fitted from chloride concentration during a 20-day chloride-nitrate coinjection (Bencala, 1984), and biotic uptake kinetics were based on flume studies by Kim et al. (1990) and Triska et al. (1983). Nitrate concentration from the 20-day coinjection experiment served as a base for model validation. The complete transport retention model reasonably predicted the observed nitrate concentration. However, simulations which lacked either the transient storage submodel or the biotic uptake submodel poorly predicted the observed nitrate concentration. Model simulations indicated that transient storage in channel and hyporrheic interstices dominated nitrate retention within the first 24 hours, whereas biotic uptake dominated thereafter. A sawtooth function for <i>V</i><sub>max</sub> ranging from 0.10 to 0.17 μg NO<sub>3</sub>-N s<sup>−1</sup> gAFDM<sup>−1</sup> (grams ash free dry mass) slightly underpredicted nitrate retention in simulations of 2–7 days. This result was reasonable since uptake by other nitrate-demanding processes were not included. The model demonstrated how ecosystem retention is an interaction between physical and biotic processes and supports the validity of coupling separate hydrodynamic and reactive submodels to established solute transport models in biological studies of fluvial ecosystems.</span></p>","language":"English","publisher":"American Geophysical Union","doi":"10.1029/92WR01229","usgsCitation":"Kim, B.K., Jackman, A.P., and Triska, F.J., 1992, Modeling biotic uptake by periphyton and transient hyporrheic storage of nitrate in a natural stream: Water Resources Research, v. 28, no. 10, p. 2743-2752, https://doi.org/10.1029/92WR01229.","productDescription":"10 p.
