If not, 2-5 L. | Prefer -80, but could be stored in the dark at room temperature depending on total P versus organic P | More water filtration conducted by Benitez-Nelson on Process ship. | Interested in measuring particulate P on all water column, pump, and sediment trap samples to examine how elemental stoichiometry changes with biological pump. | Both vessels | https://drive.google.com/open?id=1EtZiDWgCOPdJtEUyP47UdEqIax8h9Lsv | cbnelson@geol.sc.edu | Follow up with Claudia and Ben Water column samples how much water is needed? | |||||||||||||||||
4 | 3/13/2018 15:38:56 | Adrian M. | Melissa Duhaime, University of Michigan | 1. Sample Type: flow cytometry; glut-fixed seawater, 3x 2 ml (<20-40 µm pre-filter) per sample. Sample Method: tube filled (flash frozen, if possible) and stored at -80C 2. Sample Type: viral omics Sample Method: first filtration (0.2 µm; 142 mm PES), iron chloride flocculation, 2nd filtration (0.45 µm; 142 mm PES); filter storage at 4C 2x 20 L on filter 1 (0.2 µm filter with host cells), stored in 50 ml flacon @ -20C 2x 20 L on filter 2 (0.45 µm filter with virus floccs), stored in 50 ml flacon @ 4C Link to Protocol: https://umich.app.box.com/s/pyhd8uhga6zhmm9qeaim19159wnsk5fo | Nothing in addition to what is currently planned. | We will sample in parallel with the microbial (euks, bac+arch) sampling teams. The hope is that we will take their filtrate, but recognize we will require greater volumes of water. | 2x 50 ml falcon tubes per sample in 4C 2x 20 ml falcon tubes per sample in -20C 3x 2 ml cyrovials per sample at -80C | This will depend on who is sampling and bandwidth they have, but intention is for all sampling to be done by current crew. | The efficiency of the biological pump is determined by food web processes. We propose to include study of viruses to capture this major component of top down control on lower food web processes and their connection to biological pump efficiency. Using flow cytometric and 'omics (metagenomics, proteomics) approaches to capture viral abundances and diversity, we will address: Do measures of virus:host abundances, viral community composition and function, and topology of predicted virus-host ecological networks inform models of biological pump efficiency? Broadly: Virus community composition, quantification* * I found the “Funded_Measurement_Table_V6” file on the EXPORTS site. I see “including viral numbers” in FCM/Microscopy for heterotrophs and protists. If you are all set there, I won’t cover it—but happy to help if needed, we have a new FCM that’s great for virus counts, and a Bigelow-trained tech :-) Also in this table I see mention of viral infections/dilutions, mitomycin C experiments. Those are pretty neat experiments we are doing in other systems, but we can’t tackle that with only the opportunistic water collections. | Process Ship | duhaimem@umich.edu | Heterotrophs.. check with susanne MD.. | OK | |||||||||||||||||

Samples for comparison of Ba concentration and Ba isotopes in water column and suspended and sinking particles. | Hydrography and nutrients. In addition, relates most directly to 234Th and 210Po/210Pb, but as a reminerlization tracer it is linked to many other EXPORTS C flux parameters and proxies | Three 12 point profiles (coordinate with 234Th group) for water (60 ml) | No. Water stored room temp. Particles can be dried. Horner will provide containers. | Postdoc in Buesseler group will help coordinate all sampling and processing at sea (and work on analyses back at WHOI in collaboration with Horner lab) | How do upper ocean ecosystem characteristics determine the vertical transfer of organic matter from the well-lit surface ocean? This question will be tackled by measuring the abundance and isotopic composition of barium—an emerging geochemical proxy for organic carbon oxidation—in dissolved and particulate samples collected in the upper water column. | Survey Ship (& trap samples from Process ship) | thorner@whoi.edu | Talk to Meg | Ok tent | |||||||||||||||||
6 | 4/12/2018 16:12:15 | Alyson S. | Patrick Rafter, UC Irvine | Parameter: N and O isotopic composition of dissolved nitrate (NO3-) analyzed via the 'denitrifier' method. Samples require seawater from Niskin bottle that has undergone the same filtration as samples for macro-nutrient (nitrate, phosphate, silicate, etc.) measurements. It is preferred that these samples come from the same casts and bottles as the macro-nutrient measurements. However, it is ok if filtration is not available. See attached methods document. | Basic hydrography, macronutrient data, shipboard ADCP | Samples are 30 mL. A full-depth profile is requested once during the cruise, with additional profiles from the upper 400 m as available. | 0.5 cu ft of storage in -20C | Would make sense to take these on the Survey ship when macronutrients are collected, but if people are too busy I (Alyson) can try to coordinate it on the process ship. | How do upper ocean ecosystem characteristics determine the vertical transfer of organic matter from the well-lit surface ocean? | I don't care, just give me the samples | https://drive.google.com/open?id=19sKcilKq5-BtftT-3dMAJIVtfkR3Pj5D, https://drive.google.com/open?id=1YcnpV1i1NsLxNWcQPIaht6azXYsFXT1G | prafter@uci.edu | Alyson - can take over? | OK | ||||||||||||||||
