Baseline Water Quality Inventory for the Southwest Alaska Inventory and Monitoring Network, Kenai Fjords National Park Laurel A. Bennett National Park Service Southwest Alaska Inventory and Monitoring Network 240 W. 5th Avenue Anchorage, AK 99501 April 2005 Report Number: NPS/AKRSWAN/NRTR-2005/02 Funding Source: Southwest Alaska Network Inventory and Monitoring Program, National Park Service File Name: BennettL_2005_KEFJ_WQInventory_Final.doc Recommended Citation: Bennett, L. 2005. Baseline Water Quality Inventory for the Southwest Alaska Inventory and Monitoring Network, Kenai Fjords National Park. USDI National Park Service, Anchorage, AK Topic: Inventory Subtopic: Water Theme Keywords: Reports, inventory, freshwater, water quality, core parameters Placename Keywords: Alaska, Kenai Fjords National Park, Southwest Alaska Network, Aialik Bay, McCarty Fjord, Harrison Bay, Two Arm Bay, Northwestern Fjord, Nuka River, Delight Lake Kenai Fjords Water Quality Inventory - SWAN Abstract A reconnaissance level water quality inventory was conducted at Kenai Fjords National Park during May through July of 2004. This project was initiated as part of the National Park Service Vital Signs Inventory and Monitoring Program in an effort to collect water quality data in an area where little work had previously been done. The objectives were to collect baseline information on the physical and chemical characteristics of the water resources, and, where possible, relate basic water quality parameters to fish occurrence. Water temperatures in Kenai Fjords waters generally met the Alaska Department of Environmental Conservation (DEC) regulatory standards for both drinking water and growth and propagation of fish, shellfish, other aquatic life and wildlife. Water temperature standard are less than or equal to 13° C for spawning and egg and fry incubation, or less than or equal to 15° C for rearing and migration (DEC 2003). -

Changes in the timing and quantity of glacial melt also affect discharge and temperature of alpine streams. -
Tropical Ice Core Records of Changes in Symmetry, Position And/Or Intensity of the Hadley Circulation on Milankovich, Millennial, and Centennial Time Scales
Tropical ice core records of changes in symmetry, position and/or intensity of the Hadley Circulation on Milankovich, millennial, and centennial time scales. Lonnie G. Thompson, Mary E. Davis, Ellen S. Mosley_Thompson, Tracy A. Mashiotta, and Ping-nan Lin Ice core records from South America, Africa, the Himalayas and the Tibetan Plateau provide evidence of past changes in position and intensity of the Hadley circulation. Cores from seven sites at elevations greater than 5600 m asl suggest that the climate (temperature and precipitation) from either side of the equator is out of phase. These records are combined with more than 120 other paleoclimate records to produce a global map of effective moisture changes between the Last Glacial Maximum (LGM) and the Early Holocene (EH). The global pattern of changes in the tropical hydrological system between these two periods has been zonally symmetrical; for example, the zonal belts in the deep tropics that experienced greater aridity during the LGM attained maximum humidity in the EH, while at the same time the humid subtropical and mid- latitude belts generally became drier. In this paper we examine the spatial symmetry and asymmetry of these changes about the equator through time. A strong role for the Hadley circulation is suggested such that its position, its intensity, or both were altered as the Earth moved from glacial to interglacial conditions. The ice core records from these low-latitude, high-elevation sites also raise questions about; (1) the synchroneity of glaciation, (2) the relative importance of temperature and precipitation in governing the growth and decay of ice fields north and south of the equator, and; (3) the relative role that the strength and position of the Hadley circulation plays in determining the geographical distribution of low latitude ice fields. -

Ilulissat Icefjord
World Heritage Scanned Nomination File Name: 1149.pdf UNESCO Region: EUROPE AND NORTH AMERICA __________________________________________________________________________________________________ SITE NAME: Ilulissat Icefjord DATE OF INSCRIPTION: 7th July 2004 STATE PARTY: DENMARK CRITERIA: N (i) (iii) DECISION OF THE WORLD HERITAGE COMMITTEE: Excerpt from the Report of the 28th Session of the World Heritage Committee Criterion (i): The Ilulissat Icefjord is an outstanding example of a stage in the Earth’s history: the last ice age of the Quaternary Period. The ice-stream is one of the fastest (19m per day) and most active in the world. Its annual calving of over 35 cu. km of ice accounts for 10% of the production of all Greenland calf ice, more than any other glacier outside Antarctica. The glacier has been the object of scientific attention for 250 years and, along with its relative ease of accessibility, has significantly added to the understanding of ice-cap glaciology, climate change and related geomorphic processes. Criterion (iii): The combination of a huge ice sheet and a fast moving glacial ice-stream calving into a fjord covered by icebergs is a phenomenon only seen in Greenland and Antarctica. Ilulissat offers both scientists and visitors easy access for close view of the calving glacier front as it cascades down from the ice sheet and into the ice-choked fjord. The wild and highly scenic combination of rock, ice and sea, along with the dramatic sounds produced by the moving ice, combine to present a memorable natural spectacle. BRIEF DESCRIPTIONS Located on the west coast of Greenland, 250-km north of the Arctic Circle, Greenland’s Ilulissat Icefjord (40,240-ha) is the sea mouth of Sermeq Kujalleq, one of the few glaciers through which the Greenland ice cap reaches the sea. -
