Gulf Watch Alaska Nearshore Component: Monitoring Site Locations from Prince William Sound, Katmai National Park and Preserve, and Kenai Fjords National Park

These data are part of the Gulf Watch Alaska (GWA) long term monitoring program, nearshore monitoring component. Specifically, these data describe site locations for rocky intertidal, mussel sampling, soft sediment bivalve sampling, and eelgrass bed sampling in the northern Gulf of Alaska within the GWA program. The dataset consists of two comma separated files exported from a Microsoft Excel workbook. The data consists of 1. rocky intertidal, mussel sampling, and soft sediment site location information, and 2. eelgrass bed locations. Sampling will be conducted in Katmai National Park and Preserve (KATM), Kenai Fjords National Park (KEFJ), Prince William Sound (PWS) and to a lesser extent on the Lake Clark National...

Brown Bear (Ursus acrtos) Captures and Serological Survey Results for Bacterial Viral and Parasitic Agents, Alaska, 2013-2016

Dataset containing test results of screening blood and serum samples from five populations of Brown Bears in Alaska. Samples were tested to detect current or previous exposure to bacteria (Brucella spp., Francisella tularensis, and Leptospira spp.), viruses (canine adenovirus, canine distemper virus, canine parvovirus, and influenza A virus), and parasites (Toxoplasma gondii, and Trichinella spp.).

Mercury Stable Isotope Assessment of Dragonflies and Fish Tissues across United States National Parks

This dataset details mercury (Hg) stable isotope values in dragonflies and fish tissues collected across U.S. National Parks. Dragonfly samples were collected as part of the Dragonfly Mercury Project (https://geonarrative.usgs.gov/dmp/), a citizen science project focused on using dragonfly larvae as biosentinels for Hg bioaccumulation. Fish were collected as part of separate park-wide monitoring initiatives. Biological samples were collected from 2014-2019 and composited for Hg stable isotopes measurements by the U.S. Geological Survey Contaminant Ecology Research Laboratory (CERL, Corvallis, Oregon). Measurements for Hg isotopes were performed by the U.S. Geological Survey Mercury Research Laboratory (MRL, Madison,...

Assessment of mercury sources in Alaskan lake food webs (ver 1.1, September 2023)

This data release includes results of raw water, soil, seston, and fish tissue samples collected from 14 lakes within Lake Clark National Park and Katmai National Park between 2007 and 2017. Specifically, these data include total mercury and methylmercury concentrations in water, size-sieved seston, and particulate matter. Additionally, these data include soil and volcanic ash measurements from the surrounding watersheds. Finally, these data include energetic profiling of seston, lake trout (Salvelinus namaycush), and sockeye salmon (Oncorhynchus nerka) as well as mercury isotope measurements of the fishes. These data, except for Lake Clark data, were use in interpreting mercury mass balance flows and bioavailability...
