Title: Arctic Riverine CDOM and its effects on the Polar Marine Light Field

Abstract

It is well-known that CDOM (Chromophoric Dissolved Organic Matter) can have a significant effect on biological activity in the photic zones of aquatic ecosystems. However, the extent of CDOM’s interference with biological activity is not well-known. We examined this issue in great detail in the mixed surface layer of the Arctic Ocean. We studied the impacts of CDOM’s light attenuation on Arctic phytoplankton populations to discover if riverine CDOM’s presence in the Arctic ocean could inhibit and possibly prevent local phytoplankton populations from performing photosynthesis. We incorporated biogeochemistry concepts and data with oceanographic models and calculations to approach the problem. The results showed that riverine CDOM can indeed significantly impact the productivity of phytoplankton populations during the spring and summer months near the major Arctic river mouths we chose to examine. Although our study was detailed and inclusive of many variables, the issue of CDOM’s light attenuation and its effects on phytoplankton populations must be explored on a global scale to help understand if riverine CDOM could prove disastrous for phytoplankton populations.

  • This report contains the results of a literature review on the carrying capacity of Pacific salmon in the Columbia River Basin. The objective of the review was to find the information gaps relative to the determinants of salmon carrying capacity in the Columbia River Basin. The review was one activity designed to answer questions asked in Measure 7.1A of the Councils Fish and Wildlife Program. Based, in part, on the information learned during the literature review and the other work accomplished during this study the Pacific Northwest National Laboratory (PNNL) state concluded that the approach inherent in 7.1A will notmore » increase understanding of ecology, carrying capacity, or limiting factors that influence salmon under current conditions. To increase understanding of ecology, carring capacity, and limiting factors, it is necessary to deal with the complexity of the sustained performance of salmon in the Columbia River Basin. The PNNL team suggests that the regions evaluated carrying capacity from more than one view point. The PNNL team recommends that the region use the contextualistic view for evaluating capacity.« less

    The report summarizes information on the types of potential effects on marine mammals, endangered species, and rare plants which may be associated with oil and gas lease sales pending for the northern Bering Sea and arctic regions. The discussion does not imply that any specific level of impact will be sustained but rather identifies the various potential effects associated with offshore exploration, development, and production of petroleum hydrocarbon resources in the Alaska arctic regions.

    Changes of the geometry of the open-field line region (namely, the polar cap) caused by the passage of a tangential IMF discontinuity are simulated. A singly-bounded open-field line region tends to split into two, forming a narrow closed-field-line region and thus allowing the formations of a plasma sheet and of an auroral arc across the highest-latitude region of the Earth. The three-dimensional geometry of some of the closed-field lines in the narrow closed region is examined. In this connection, an interesting observation of the formation of an auroral arc, over Thule, Greenland, is reported.

  • Experimental protocols and a study on the biological effects of ingesting Prudhoe crude oil by reindeer/caribou have been completed (Section II-C) and in addition, two lengthy feeding trials (4 to 5 months duration) were conducted with reindeer at the Cantwell Reindeer Research Station. In the 1976 experiment, we studied the physiological responses of reindeer that were fed grasshays identical to those being used in Alaska to revegetate transportational corridors and in a similar study in winter 1976/77, we made special effort to establish criteria for use in determining the physiological status of reindeer and/or caribou when they are confronted withmore » environmental and/or nutritional stresses. The long-term nature of these experiments made possible extensive studies of the basic food habits and preferences of reindeer and caribou. Work on effects of nutritional and environmental factors on the accumulation and metabolism of radiocesium includes fallout radiocesium concentrations in environmental samples and forage intake by reindeer/caribou as estimated by the radiocesium model. This study represents an interesting application of the radioisotope technique for quantitative assessment of radionuclide transfer in predator prey food chains.« less
