Although the gross pattern of worldwide seismicity contributed to the formulation of the plate tectonic hypothesis, it is the space-time characteristics of this seismicity that may contribute more toward understanding the kinematics and dynamics of the driving mechanism long speculated to originate in the mantle. If the lithosphere is composed of plates that move essentially as rigid bodies, then there should be seismic edge effects associated with this movement. It is these interplate effects, especially seismic migration patterns, that we discuss here. The unidirectional propagation at constant velocity (80 km yr<sup>−1</sup><span>&nbsp;</span>east to west) for earthquakes (<i>M</i>≥7.2) on the Antblian fault for the period 1939 to 1956 (ref. 2) is one of the earliest observations of such a phenomenon. Similar studies<sup>3,4</sup><span>&nbsp;</span>of the Alaska Aleutian seismic zone and certain regions of the west coast of South America suggest unidirectional and recurring migrations of earthquakes (<i>M</i>≥7.7) occur in these areas. Between these two regions along the great transform faults of the west coast of North America, there is some evidence<sup>5</sup><span>&nbsp;</span>for unidirectional, constant velocity and recurrent migration of great earthquakes. The small population of earthquakes (M&gt;7.2) in Savage's investigation<sup>5</sup><span>&nbsp;</span>indicates a large spatial gap along the San Andreas system in central California from 1830 to 1970.

The dominant gaseous species present, even for relatively oxidizing buffers such as the QFM buffer, are H<sub>2</sub>O and H<sub>2</sub>; the main problem is to calculate the chemical potentials of these components in a binary mixture. The mixing of these two species in the gas phase was assumed by Eugster and Wones (1962) to be ideal; this assumption allows calculation of the chemical potentials of the two components in a binary gas mixture, using data in the literature. A simple-mixture model of nonideal mixing, such as that proposed by Shaw (1967), can also be combined with the equations of state for oxygen buffers to permit derivation of the chemical potentials of the two components. The two mixing models yield closely comparable results for the more oxidizing buffers such as the QFM buffer. For reducing buffers such as IQF, the nonideal-mixing correction can be significant and the Shaw model is better.</p><p>The procedure of calculation of mineralogical thermochemical data, in reactions where hydrogen and H<sub>2</sub>O simultaneously appear, is applied to the experimental data on annite, given by Wones<span>&nbsp;</span><i>et al.</i><span>&nbsp;</span>(1971), and on almandine, given by Hsu (1968).

Reef organisms may play a major role in the transport and distribution of sediment on the sea floor adjacent to coral reefs. 2. Some fish such as Malacanthus plumieri (Bloch) selectively transport and collect certain types of sediment (such as larger coral and shell fragments). 3. The random movement of crawling or burrowing organisms may cause a large amount of sediment to be shifted laterally on the sea floor. On slopes, a net downhill displacement may result. 4. The surface configuration and internal structure of the sediment is rapidly changed by faunal mixing. Ripple marks formed by waves or currents are obliterated by the activity of organisms in only a few weeks in the environment studied. Internal structure (bedding) near the sediment-water interface is similarly destroyed in a short period of time. 5. Larger clasts (including empty shells) on the sea floor tend to be buried by faunal undermining. The rate of burial depends primarily on the grain size of the substrate. 6. The random movement of fauna on the sea floor may produce a predominantly concave-up orientation of pelecypod shells and shell fragments on the sea floor - the opposite of that produced by the activity of waves or currents. ?? 1973 Biologischen Anstalt Helgoland.","language":"English","publisher":"Springer-Verlag","doi":"10.1007/BF01609502","usgsCitation":"Clifton, H., 1973, Role of reef fauna in sediment transport and distribution - Studies from Tektite I and II: Helgoländer Wissenschaftliche Meeresuntersuchungen, v. 24, no. 1-4, p. 91-101, https://doi.org/10.1007/BF01609502.","productDescription":"11 p.","startPage":"91","endPage":"101","costCenters":[],"links":[{"id":480653,"rank":1,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1007/bf01609502","text":"Publisher Index Page"},{"id":203289,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"24","issue":"1-4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a0ee4b07f02db5fe281","contributors":{"authors":[{"text":"Clifton, H.E.","contributorId":44151,"corporation":false,"usgs":true,"family":"Clifton","given":"H.E.","affiliations":[],"preferred":false,"id":346748,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

The wintering off-shore avifauna was found to be impressively rich in variety of species and numbers of individuals.  Sightings included Fulmar and Skua, both first sight records for Maryland.  Large alcids, especially Razorbills, were observed in unprecedented numbers and on five of the seven trips undertaken.  Thick-billed Murre was sighted once and Dovekie, once.  A Pomarine Jaeger was a mid-winter first for Maryland.  Black-legged Kittiwakes were sighted on all seven trips, with age ratios consistently averaging about three adults to one immature.  Likewise, Gannets were observed on all seven trips, 7.5 adults to one immature.  Iceland Gulls were seen twice and Black-headed Gulls on three trips.  Evidence of a definite migration was noted on Nov. 19, as Gannets were observed flying south in a narrow band, four miles wide, five to nine miles east of Ocean City, and Black-legged Kittiwakes, likewise, were heading south in a steady stream no closer than 14 miles east of Ocean City.  Data accumulated from December through March suggest most pelagics occurring in Maryland waters during this period were truly wintering and not transients.  This report is concerned primarily with the true pelagics normally found well away from the sight of land and does not dwell on those 'sea birds' commonly seen in immediate coastal waters.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Maryland Birdlife","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","collaboration":"6625_Rowlett.pdf","usgsCitation":"Rowlett, R., 1973, Sea birds wintering off Maryland shores, 1972-73: Maryland Birdlife, v. 29, no. 3, p. 88-102.","productDescription":"88-102","startPage":"88","endPage":"102","numberOfPages":"15","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":203159,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"29","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a0ce4b07f02db5fc5e0","contributors":{"authors":[{"text":"Rowlett, R.A.","contributorId":94418,"corporation":false,"usgs":true,"family":"Rowlett","given":"R.A.","affiliations":[],"preferred":false,"id":342376,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Residue concentrations in the nearly dry eggs can be greatly exaggerated by this artifact.  Valid interpretation of residue data depends upon compensation for these losses.  A method is presented for making adjustments on the basis of volume of the egg, and formulas are derived for estimating the volume of eggs of eagles, ospreys, and pelicans from egg measurements.  The possibility of adjustments on the basis of percentage of moisture, solids, or fat in fresh eggs is discussed also.","language":"English","publisher":"Springer","doi":"10.1007/BF01684824","usgsCitation":"Stickel, L., Wiemeyer, S.N., and Blus, L.J., 1973, Pesticide residues in eggs of wild birds: Adjustment for loss of moisture and lipid: Bulletin of Environmental Contamination and Toxicology, v. 9, no. 4, p. 193-196, https://doi.org/10.1007/BF01684824.","productDescription":"4 p.","startPage":"193","endPage":"196","numberOfPages":"4","costCenters":[{"id":531,"text":"Patuxent Wildlife Research Center","active":true,"usgs":true}],"links":[{"id":193531,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"9","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ae0e4b07f02db68837a","contributors":{"authors":[{"text":"Stickel, L.F.","contributorId":41095,"corporation":false,"usgs":true,"family":"Stickel","given":"L.F.","email":"","affiliations":[],"preferred":false,"id":333323,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Wiemeyer, Stanley N.","contributorId":78279,"corporation":false,"usgs":true,"family":"Wiemeyer","given":"Stanley","email":"","middleInitial":"N.","affiliations":[],"preferred":false,"id":333324,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Blus, L.
