Summary of Field Work: |
Water sampling at established stations in the Palmer LTER domain off the West Antarctic Peninsula. Samples would be collected using the ship's rosette sampler/CTD at approximately 3 depths per station, to be chosen in consultation with the cruise's Chief Scientist, but nominally at 10, 50 and 400 m depth over the continental shelf and from 1500 m off the shelf. Water samples (2 L from each depth) will be processed in the dry lab (as long as a sink is available). Processing includes filtration for RNA and DNA samples, dissolved inorganic nitrogen and urea analysis (urea and ammonium samples to be processed onboard). Filtered samples (filters and water samples) will be frozen at -80C for subsequent processing ashore. In addition, replicate incubations (250 mL bottles) with 15N-labeled substrates will be set up and run for 48 hr, then preserved by freezing at -80. We will also measure dark NaH14CO3 incorporation to estimate total heterotrophy. |
