Riverine exports of organic and inorganic carbon (OC, IC) to oceans are intricately linked to processes occurring on land. Across high latitudes, thawing permafrost, alteration of hydrologic flow paths, and changes in vegetation may all affect this flux, with subsequent implications for regional and global carbon (C) budgets. Using a unique, multi-decadal dataset of continuous discharge coupled with water chemistry measurements for the Mackenzie River, we show major increases in dissolved OC (DOC) and IC (as alkalinity) fluxes since the early 1970s, for a watershed that covers 1.8 M km2 of northwestern Canada, and provides substantial inputs of freshwater and biogeochemical constituents to the Arctic Ocean.

OBIS-USA brings together marine biological occurrence data – recorded observations of identifiable marine species at a known time and place, collected primarily from U.S. Waters or with U.S. funding. Coordinated by the Science Analytics and Synthesis (SAS) Program of the United States Geological Survey (USGS), OBIS-USA, strives to meet national data integration and dissemination needs for marine data about organisms and ecosystems. OBIS-USA is part of an international data sharing network (Ocean Biogeographic Information System, OBIS) coordinated by the Intergovernmental Oceanographic Commission, of UNESCO (United Nations Educational, Science and Cultural Organization) International Oceanographic Data and Information...

Typed information accompanying slide: The Lamont trailer moved and leveled. June 1969. 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 negative: Stu on stilts: One of the crew made stilts and walked around the ice. 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.

Handwritten information on back of photograph: 02/25/63, T-3. Cook shack - sitting with me are Arthur and Johnny (at table), 2 of the Eskimos working with us (in background). Additional information obtained from Dr. Carolyn Ruppel, Chief, U.S. Geological Survey's Gas Hydrates Project: These were likely taken during the setup phase for the laboratory "hut". I don't see in these photos any of the equipment that would have been in the hydrohut. We seem to be seeing the stove (left) and work table, but not the high bay where the piston core/heat flow probe would have been on a winch with thousands of meters of cable to lower the gear to the seafloor. It is likely that the "Eskimos" referred to for this photo were...

Typed information accompanying slide: Five camp members decided to hike across the ice island to the high spot which could be seen from camp. The day wa sunny when they started on the two to three mile walk. Everyone wore hip boots. Small lakes dotted the path. June 1969. Similar to C-29, C-31, C-35. Links to these images listed in Web Links below. 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 slides: Wreckage of abandoned huts, empty diesel drums, garbage, everything emerged out of the snow by the end of June. The ground was coated with soot from the generator smoke. June 1969. Similar to C-24. Link to this image listed in Web Links below. 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.

Typed information accompanying negative: T-3 camp in August 1969: The USGS trailer is in the left center foreground. The high spot in the right side background might be the rock pile show in earlier photos but now covering with snow. This photo is likely taken from the top of the Lamont hydrohut tower. 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.

Typed information accompanying negatives: Bob Sutton was the camp manager during the summer of 1969. He was soft spoken, experienced, and very capable. In mid-summer he developed an abscessed tooth and suffered for several days before it was controlled with penicillin from the medical supplies. There were no medical personnel on T-3, so if a medical problem developed it was handled over the radio. There were days when the radio communication was poor or non-existent. Note: T-3 Photographs - Roll F B&W negatives - June paradrop, 1969. There were three paradrops during the summer of 1969 performed by Navy C-130 planes from Elmendorf Air Force Base in Fairbanks, Alaska. These are described in this website, http://www.firebirds.org/menu2/t3/t3_p02.htm...

Typed information accompanying photograph: Slide and print: USGS hydrohut, April 1969. Taken from the ground just outside the Lamont hydrohut. Note: T-3 Photographs - Roll B - Color slides April 1969. These photos were developed into Ektachrome slides in May of 1969. Some have deteriorated. Some were printed as color prints and these may be in better condition than the slides. A few slides were copied into Kodacolor slides. Some images are missing. Photos by Dave Scoboria.

Typed information accompanying slide: A wide shallow lake. At the edge of the lake there is fresh water on top of ice island, water a foot or so deep. One of the camp members walked far out on the lake. June 1969. Similar to C-32 and C-33. Links to these images listed in Web Links below. Note: T-3 Color slides - Roll C - Color slides June 1969.

Typed information accompanying negative: Final load Note: T-3 Photographs - Roll F B&W negatives - June paradrop, 1969. There were three paradrops during the summer of 1969 performed by Navy C-130 planes from Elmendorf Air Force Base in Fairbanks, Alaska. These are described in this website, http://www.firebirds.org/menu2/t3/t3_p02.htm On the receiving end of the paradrops on T-3, these days were the high points of the summer season. This roll documents the first paradrop, which occurred in late June on a cloudy day. The loads were delivered on target to the camp runway without mishap. The second paradrop was similar, one month later. The day of the third paradrop was windy and the sky was overcast. We did not...

Typed information accompanying negative: The landscape and hydrohut in July. By mid July the weather was starting to grow colder. The snow had melted and the lakes were drying up. Note: T-3 Photographs - Roll G B&W negatives – July 4,1969 This roll of photographs was mostly taken on July 4, 1969. There was a camp get together and celebration that day. There was no alcohol on T-3 at that point. Bob Sutton chose an abandoned hut to burn and that event was the high point of the day. (Photos on Roll G taken by Dave Scorboria)
