We summarize available information on Pacific walrus haulouts from available reports, interviews with coastal residents and aviators, and personal observations of the authors. We provide this in the form of a georeferenced database that may be queried and displayed with standard geographic information system and database management software. The database contains 150 records of Pacific walrus haulouts, with a summary of basic characteristics on maximum haulout size, age-sex composition, season of use, and decade of most recent use. Citations to reports are provided as a bibliographic database.

Typed information accompanying slides: This view is of personnel leaving on June 6, 1969. Note: Dave Scoboria returned to T-3 about June 1, 1969. A number of new personnel arrived for the summer season and others left. Note: T-3 Color slides - Roll C - Color slides June 1969. These photos were taken between June 6, 1969 and June 27, 1969 and developed in late 1969 into Kodacolor slides after returning from T-3. One slide has deteriorated. Photos by Dave Scoboria, except for C-6.

Typed information accompanying photograph: Slide and print. Garbage dump in winter. Mostly diesel drums. Note: T-3 Photographs - Roll A - Color slides February - March 1969. These photos were taken during February and March of 1969 and developed into Ektachrome slides in May of 1969. Some have deteroriated. When the slides were new some of them were printed as color prints. Some prints don't have matching slides. A few slides were copied as Kodacolor slides some time during the 1970s and there are some duplicate slides. The Kodacolor slides have not deteriorated. Some images are missing.

The T-3 (Fletcher's) Ice Island in the Arctic Ocean was the site of a scientific research station re-established by the Naval Arctic Research Laboratory starting in 1962. Lamont Geological Observatory (LGO; now Lamont-Doherty Earth Observatory) and the U.S. Geological Survey, along with other organizations, ran research laboratories on the island during the 1960s and early 1970s as the island drifted in the Amerasian Basin. LGO compiled navigational data, measured gravity and magnetic data, and conducted seismic surveys to image the seafloor. This data release provides the edited LGO-compiled 1 hour navigational data for T-3 from May 1962 until September 1974, along with gravity and magnetic data and calculated...

The T-3 (Fletcher's) Ice Island in the Arctic Ocean was the site of a scientific research station re-established by the Naval Arctic Research Laboratory starting in 1962. Starting in 1963, the USGS acquired marine heat flow data and coincident sediment cores at sites in Canada Basin, Nautilus Basin, Mendeleev Ridge, and Alpha Ridge as the ice island drifted in the Amerasian Basin. Radiogenic heat content in sediments can be an important contributor to measured heat flow. The USGS therefore measured radiogenic heat content in sediments recovered at 26 of the attempted/successful heat flow measurement sites using the laboratory methods available at the time. This dataset reports the measured radiogenic heat values...

The U.S. Geological Survey recovered 9 piston cores from theNorthwind Ridge in the Canada Basin of the Arctic Ocean from acruise of the USCGC Polar Star during 1988. Preliminaryanalysis of the cores suggests sediments deposited onNorthwind Ridge preserve a detailed record of glacial andinterglacial cycles for the last few hundred-thousand to onemillion years. This report includes quantitative data onforaminifers and selected sediment size-fraction data insamples from Northwind Ridge core PI-88AR P5.

The Sea Surface Temperature (SST) data of the Arctic show temperature ranges in degrees C using points whose locations correspond to the centroids of AVHRR Pathfinder version 5 monthly, global, 4 km data set (PFSST V50). The pathfinder rasters are available from the NOAA National Oceanographic Data Center (NODC) and from the Physical Oceanography Distributed Active Archive Center (PO.DAAC), hosted by NASA JPL. Furthermore, each point in the SST dataset is categorized by the ecoregion in which it is located. This classification is based on the Marine Ecosystems Of the World (MEOW) developed and distributed by The Nature Conservancy. These data have been QA'd in that we have selected only data values with associated...

Typed information accompanying negative: The ice boat: Several of the crew constructed an ice boat with sails made from parachutes. These photos show the ice boat in action. Note: T-3 Photographs - Roll I B&W negatives – August-September 1969 This roll shows activities during August and September 1969 on T-3. The summer season had now lasted two months. The weather grew cold. Photos by Dave Scorboria.
