This dataset comprises ultrahigh resolution mass spectrometry (Fourier-transform ion cyclotron resonance mass spectrometer, FT-ICR-MS) data and molecular indicies calculated from these data (IPhoto, IDeg, IBio). -78.48554 -64.39954 -69.82935 -64.60813 -72.29779625026661 -67.2448071427923 2023-01-04T10:11:30 2023-01-28T12:04:28 2.410836735 3050.243327 irregular surface Palmer-LTER Palmer Long-Term Ecological Research https://pallter.marine.rutgers.edu/ German Research Foundation DFG http://www.dfg.de/en/ https://doi.org/10.13039/501100001659 390741603 EXC 2077: The Ocean Floor – Earth's Uncharted Interface https://gepris.dfg.de/project/390741603 National Science Foundation NSF https://doi.org/10.13039/100000001 0217282 Palmer Long-Term Ecological Research https://www.nsf.gov/awardsearch/show-award/.do?AwardNumber=0217282 National Science Foundation NSF https://doi.org/10.13039/100000001 0823101 Palmer Long-Term Ecological Research https://www.nsf.gov/awardsearch/show-award/.do?AwardNumber=0823101 National Science Foundation NSF https://doi.org/10.13039/100000001 1440435 Palmer Long-Term Ecological Research https://www.nsf.gov/awardsearch/show-award/?AWD_ID=1440435 National Science Foundation NSF https://doi.org/10.13039/100000001 9011927 Palmer Long-Term Ecological Research https://www.nsf.gov/awardsearch/show-award/.do?AwardNumber=9011927 National Science Foundation NSF https://doi.org/10.13039/100000001 9632763 Palmer Long-Term Ecological Research https://www.nsf.gov/awardsearch/show-award/.do?AwardNumber=9632763 National Science Foundation NSF https://doi.org/10.13039/100000001 OPP-2026045 ANT Integrated System Sciences https://www.nsf.gov/awardsearch/show-award/?AWD_ID=2026045 Natural Environment Research Council NERC http://www.nerc.ac.uk/ https://doi.org/10.13039/501100000270 NE/S007407/1 E4: Edinburgh Earth, Ecology and Environment Doctoral Training Partnership LMG2301_C1 -64.93262 -64.39954 Southern Ocean -1300.0 2023-01-04T10:11:30 LMG2301 LMG23-01 Punta Arenas, Chile 2022-12-23T00:00:00 2023-02-06T00:00:00 Laurence M.
