ABSTRACT

Sea surface temperature surveyswere conducted weekly off SanDiego. Calif.. using an airborne in­frared radiometer from Aprilthrough October 1972-74. A total of90 su rveys were made over the320-mile Hight track. The analogchart record of temperature waskeyed to a .. ground truth" tempera­ture measurement and read to deter­mine I min average temperatureswhich were plotted on the Highttrack and I OF (0.56 °C) isothermswere contoured from the data. Thetrend of sea surface temperaturesduring the 3-year period showedwarmer temperatures in 1972. whichwas an "el Nino" year. cooler in1973. warmer than 1973 in 1974.but not as warm as 1972. In earlyJuly 1974. an anomalous warmingperiod occurred and highest averagetemperatures of n OF (22. rC) wererecorded in 19 July 1974. Lowestaverage temperature of 54°F(12.2°C) was recorded on 2 April1973.

The 1972-74 survey temperaturestaken over the "ground truth" cali­bration site were compared with atime series of temperature observa­tions taken during the same monthsfrom 1963 to 1%8. The averagetemperature during 1963-68 was63.4°F (17.4°C) and for 1972-74.

ABSTRACT

Spring (1968-75) and autumn(1963-75) bottom-water tempera­ture temperatures in the Gulf ofMaine and on Georges Bank wereanalyzed to investigate a suspectedwarming trend in the region. Duringthe spring the mean temperature inthe Gulf of Maine increased rathersteadily from a Jaw of 5.4°c in 1968to a high of6.4°C in 1974. Varioussubareas of the Gulf had more fre­quent and greater oscillations butexhibited the same overall warmingtrend. Mean spri ng temperatures onGeorges Bank fluctuated from 3.8°Cin 1968 to 6.3°C in 1974 and de­clined by nearly 2°C in 1975 withsimilar characteristics in eastern.central. and western subareas of theBank.

During the autumn in the Gulf.bottom-water temperatures reacheda minimum of 5.4 °c in 1966. in­creased to a maximum of 8.4°C in1973 and 1974. but declined to8.0°C in 1975. Subareas of the Gulf

generally showed the ~ame tempera­ture trends from 1963 to 1968; espe­cially notable are the cooling trendwest of long. 69°W which com­menced in 1971. and a decrease inall five subareas in 1975. GeorgesBank temperatures in autumn de­cl ined from a maximum of 13. I°c in1965 to a minimum of lOA°c in1969. reached another peak of12.6°C in both 1973 and 1974. butdeclined to 11.6°C in 1975. Sub­areas of Georges Bank generally fol­lowed the same pattern with theeastern third of the Bank usually 2°Cor colder than either of the other sub­areas in the autumn.

The averaoe bottom-water tem­peratures during spring were 5.0°Con Georges Bank and 6.1 °c in·theGulf of Maine: temperatures in theautumn were II.rC and 7.2°C. re­spectively. for these areas.

ABSTRACT

Tilefishes have been examined ona world basis with the followingconclusions: I) Tilefishes belong totwo distinct phyletic lines here des­ignated as the family Branchio­stegidae and the resurrected familyMalacanthidae. 2) The Branchio­stegidae include 3 genera and 21species. 3) The Malacanthidae in­clude 2 genera, 2 subgenera. and 8species. 4) A new species. Caulo/a­fi/us hubbsi. is described from offsouthern California. the Gulf ofCalifornia, the Galapagos Islands.and from Callao, Peru; it is generallyfound sympatrically with the othertwo eastern Pacific species ofCau/o/afi/us. 5) A second newspecies. Branchiosfegus a/bus. isdescribed from off central Honshu.Japan; Pusan. Korea; along the coastof the East China Sea includingShanghai and Taiwan; and the coastsof the South China Sea includingHong Kong and Macao. Branchio­sfegus a/bus was formerly confusedwith B. argentafus Cuvier 1830. 6)Branchiostegids are generally rela­tively deep dwelling (20-600 m;

ABSTRACT

Trace element levels have beendetermined in tissues of 204 speciesof finfish. Mollusca. <lnd Crustaceataken from 198 sites around thecoastal United States. indudingAlaska and Hawaii. The survey wasundertaken as part of the Microcon­stituents Program of the NationalMarine Fishe~ies Service, and cov­ers the occurrence of 15 elements:antimony. arsenic, cadmium,chromium. copper, lead, manga­nese, mercury, molybdenum, nick­el, selenium. silver. tin, vanadium.and zinc. Total concentraions ofeach element were determined with­out regard to chemical form. Thespecies analyzed represent approxi­mately 93 percent of the volume ofthe U.S. commercial and sportfishcatch. The analytical data are sum­marized in several ways in order toemphasize different aspects of thetrace element distributions. Meanlevels of each element are presentedin relation to the number of speciesexamined, the U.S. (commercialand sportfish) catch, and the U. S.catch intended for consumption.More detailed analytical data on all15 elements are given for individualspecies with reference to tissueanalyzed, length and weight of fish,
