Chlorophyll data from McMurdo Sound, Antarctica Dataset Description: <p>This dataset includes chlorophyll, phaeopigments, depth, lat, lon, and station from McMurdo Sound, Antarctica collected between the austral years 2012/2013 and 2014/2015.</p> Methods and Sampling: <p>Small holes were drilled through the McMurdo Sound fast ice. A Niskin Bottle was deployed below the fast ice and water was collected just below the ice-water interface and at a pre-determined depth (Chlorophyll maximum) as determined by a fluorescence sensor on a CTD. Water samples from the Niskin bottles were collected in 4 L amber Nalgene bottles and then immediately stored in a dark cooler. Gloves were worn for sample collection and bottles and caps were rinsed three times before sample collection. The sample bottles were immediately processed as soon as they returned from the field. The collection bottle was gently swirled and 50 to 2000 mL were filtered under low vacuum onto a 25 mm GF/F filter. Filters were immediately placed in 13 mm borosilicate test tubes containing 7 mL 90% v/v HPLC grade acetone and extracted in the dark for 24 h at -20 degrees C. After extraction, fluorescence was measured with a Turner Designs 10 AU fluorometer before and after acidification. The fluorometer was calibrated at McMurdo Station at the beginning of the field season using Chlorophyll a standards from Sigma-Aldrich and rechecked using a solid standard from Turner Designs several times during the field season. Chlorophyll a was determined using the methods of Parsons et al. (1984).</p>

Food web dynamics in an intact ecosystem: the role of top predators in McMurdo Sound

Food web dynamics in an intact ecosystem: the role of top predators in McMurdo Sound
<p><em>Extracted from the NSF award abstract:</em></p>
<p>The research project investigates the importance of top down forcing on pelagic food webs. The relatively pristine Ross Sea includes large populations of upper-level predators such as minke and killer whales, Adélie and Emperor penguins, and Antarctic toothfish. This project focuses on food web interactions of Adélie penguins, minke whales, and the fish-eating Ross Sea killer whales, all of which exert foraging pressure on their main prey, crystal krill (<em>Euphausia cyrstallorophias</em>) and silver fish (<em>Pleuragramma antarcticum</em>) in McMurdo Sound.</p>
<p>The investigators used a video- and acoustic-capable ROV, and standard biological and environmental sensors to quantify the abundance and distribution of phytoplankton, sea ice biota, prey, and relevant habitat data. The sampling area included 37 stations across an 30 x 15 km section of McMurdo Sound, stratified by distance from the ice edge as a proxy for air-breathing predator access. This study will be among the first to assess top-down forcing in the Ross Sea ecosystem and will form the basis for multidisciplinary studies in the future.</p>
