Science objectives1. Water column sampling at two basins: Discovery and Urania Basins, at 3 depths: brine (approx 3500-4000m depth), halocline (~3500m), and reference (~2000m) using a new sampler, the SID-ISMS (under construction). Niskin rosette as backup.
2. Sediment coring at both basins, using ROV Jason. Cores will be collected in 3 locations for each basin, the "bathtub ring" where the halocline impinges on the seafloor, the brine, and a reference core sample from above the halocline.
Science Activities1. Water column sampling using the SID-ISMS to collect in situ filtered water (ship must hold position during deployment while instrument is working) and preserved in situ for molecular work.
2. Water column sampling using the SID-ISMS to collect in situ filtered and preserved samples for FISH/microscopy experiments.
3. Grazing experiment using SID-ISMS to collect water from halocline of each basin and measure the grazing rates of protozoa over a 6 hour period. Instrument must stay down at depth during the 6 hours. Sampler can be lifted to ~3000 m depth to get it away from the bottom., but ship must stay in position to avoid dragging the sampler
4. Coring of "bathtub ring" at each basin using the ROV Jason which will be used to locate the bathtub ring and then collect cores at that location.
5. Coring of brine at each basin. ROV Jason will reach into the brine from the bathtub ring area and will collect cores. Corers will be a combination of large Jason pushcores (Bernhard owns a number of these and will bring them) and also some "Tim Shank type RNAlater samplers". These need to be fabricated (and perhaps some borrowed from Shank).
6. Coring of a reference sample from outside the halocline (above) at each basin (normal seawater sediments).

Will you be using Long Base Line (LBL) navigation? no
Will you be using Ultra-short baseline (USBL) navigation for other than Alvin operations? no
Navigation Notes: I am not up on exactly what Jason needs, but I know it used to be LBL, but seem to recall Jason uses USBL now? We may need to set out transponders.
WinchesCTD Winch with .322" Electro-mechanical wire
Trawl Winch with 9/16th trawl wire
Wire use and applicationCTD Winch with .322" Electro-mechanical wire
Wire Notes: This wire (the regular CTD wire) will be used for the SID/ISMS, which has real-time communication features. The instrument is capable of carrying up to 8L of water. The rest of the instrument is filter units. Edgcomb can not provide an exact weight at this time since it is under construction, but it is far lighter than a Niskin rosette
