     "text": "Red-throated loon (Gavia stellata) populations have declined on the North Slope of Alaska, an area requiring ongoing and new management decisions related to oil and gas development. Given that adult red-throated loons have high survival rates, the declining population suggests that reproductive success is poor. Nesting red-throated loons forage in marine waters, unlike sympatric freshwater feeding loon species with stable or increasing populations. The USGS Alaska Science Center is conducting an integrative study of fish and loons at two locations along the Beaufort Sea coast over three field years (2021\u20132023). This study will not only evaluate possible drivers of the decline in loon numbers on the North Slope but inform the Bureau of Ocean Management (BOEM) about loon and fish habitats."

     "text": "This work will necessitate two separate, coordinated field efforts (see study area map). One field effort will take place at loon nesting sites on small coastal lakes and include installing time-lapse cameras to estimate loon breeding success, loon captures to deploy GPS transmitters to record loon movements and foraging activities, and tissue collections to assess loon diet. A second field effort will take place in the nearshore and coastal marine areas where breeding loons forage. Boat based sampling in river plume and marine waters will quantify fish catch rates and community composition along beaches and in coastal waters up to 20 m deep. All fish sampling will include concurrent measurements of temperature and salinity. A subset of fish will be sacrificed for tissue collections to support loon diet assessment."
