Georgia # Neutral Lipid fluxes, Indented Rotary Sphere (IRS) Floating Sediment Traps # Thomas Thompson cruise TT011, Aug 5 - Sep 18, 1992 # # Neutral lipid names have been abbreviated and prefixed with (nl_). This # prefix must be ignored when deciphering the true neutral lipid name. See # lipid.doc file for the list of full lipid names. # # The field labels 12N thru 12S are nominal latitudes for trap deployments # along 140 west. # # Traps deployed at 100 meters for durations of 1.5 to 2.5 days. For specifics # on trap deployment/recovery positions and times see event log, PI Hedges. # Methodology: Sediment trap material was filtered onto 90 mm glass fiber filters (A/E) and frozen. Filters with trap material and sediments were Soxhlet extracted with methylene chloride-methanol (2:1) and the extracts partitioned into the organic phase with 5% NaCl. The "lipid extracts" were saponified with 0.5N KOH/methanol, with "neutral lipids" extracted out of basic solution and "acids" extracted out of acidic solution. Neutral lipids were silylated with BSTFA and fatty acids were methylated with diazomethane. Anaylsis was by gas chromatography and gas chromatography-mass spectrometry. # neutral lipid fluxes = reported as ng/m^2/day # nd = no/bad data # neutral_lipids_____ 12N___ 9N____ 5N_____ 2N_____ 1N____ EQ____ 2S____ 3S____ 5S____ 12S___ nl_14ROH 12000 4000 5500 6100 6500 1600 6700 5000 4000 2200 nl_2-6-10-TMP-one nd nd 0 0 0 nd nd nd nd 0 nl_15ROH 2000 1100 2300 3500 3600 1800 2800 500 2400 1070 nl_16ROH 37100 28000 63300 90000 88000 20000 84000 75000 87000 15200 nl_17ROH 1600 1150 2000 4000 4200 2500 5000 3600 3500 1000 nl_18ROH 4100 2600 1000 9100 9300 3500 11000 7500 7600 2580 nl_phytol 2000 2800 6900 13000 7300 5400 20000 5600 5200 2760 nl_19ROH nd 300 1000 2000 500 0 2300 1000 1000 500 nl_20:1ROH nd 0 0 0 0 0 2000 0 nd 0 nl_20ROH 1300 1300 5600 17600 7000 3000 7600 2780 2700 1900 nl_21ROH nd 700 2000 4000 0 0 2000 1000 nd 1000 nl_22:1ROH nd 0 0 0 0 0 0 0 nd 0 nl_22ROH 5200 7500 32500 6000 22000 11110 26700 12300 22000 12900 nl_23ROH 900 500 2900 1500 2000 1100 3000 1500 nd 800 nl_27HC nd 0 0 0 0 0 0 0 nd 0 nl_24:1ROH nd 0 0 0 0 0 0 0 nd 0 nl_24ROH 1100 1500 11300 14000 5000 4300 3300 4600 5300 4000 nl_28HC nd 0 0 0 0 0 0 nd nd 0 nl_squalene nd 0 0 0 0 0 0 nd nd 0 nl_25ROH nd 0 0 0 0 0 0 nd nd 0 nl_29HC nd 0 0 0 0 0 0 nd nd 0 nl_26ROH nd 0 0 0 0 0 0 nd nd 0 nl_30HC nd 0 0 0 0 0 0 nd nd 0 nl_27ROH nd 0 0 0 0 0 0 nd nd 0 nl_31HC nd 0 0 0 0 0 0 nd nd 0 nl_26(5-22) 1800 1400 10300 10600 5000 3200 4700 5000 6400 1740 nl_27-NOR-(5-22) 6000 1900 20000 19000 10000 7000 11000 11000 20000 9000 nl_27(5-22) 25300 21100 148000 132000 64000 41000 82000 70000 90000 38000 nl_27(22) 4660 1400 28500 15000 8000 4000 9700 10000 13000 5200 nl_28ROH nd nd nd 0 0 nd nd nd nd 0 nl_27(5) 86800 115000 664000 401000 216700 160000 234400 215000 239000 98100 nl_27(0) 8000 10000 52000 38000 14300 8400 18000 18000 19600 6670 nl_bisnorhopane 0 nd 0 0 0 0 0 nd nd nd nl_27(5-24) 3000 4800 18000 19000 8000 3000 8000 2700 11000 2000 nl_28(5-22) 25300 13200 127400 129000 63000 42000 93000 80000 77100 36000 nl_28(22) 6400 3800 37000 27000 11300 6300 18200 15000 15000 6000 nl_27(4-en-3-one) nd 0 0 0 nd 0 0 nd nd 0 nl_28(5-24(28)) 10000 8200 156000 151000 61000 41000 75000 72000 80200 23400 nl_28(5) 1000 2000 18000 44000 10000 4500 9500 14000 14000 5600 nl_28(22) 7350 1950 50000 48000 16000 7500 18000 23000 22000 3600 nl_28-diol nd nd 0 0 0 0 0 nd nd nd nl_29(5-22) 5500 2800 23000 20000 9000 5000 15000 9000 12100 5700 nl_DM-29(5-22) 1300 500 5800 5500 1700 1000 3000 3000 3000 1300 nl_29(5) 8400 5800 43000 51000 21400 16000 37300 25000 29100 15200 nl_29(0) 2300 800 11000 8000 3000 1000 5300 4500 4300 2400 nl_29(5-24(28)) 2000 2200 13000 31000 8000 8500 16000 13000 12000 5360 nl_30(22) 2000 1000 8000 9000 3200 1300 4800 2800 4000 1600 nl_29(5-24(28)) 1100 1400 11800 4000 6500 4000 8700 7000 1400 2500 nl_30(0) 1180 1800 1400 4000 0 1000 1500 1600 500 0 nl_30-diol nd nd 0 0 0 0 nd nd nd nd 30-keto-ol nd nd 0 0 0 0 nd nd nd nd nl_homohopane nd nd 0 0 0 0 nd nd nd nd nl_37:2_alkenone nd 0 0 3000 0 2400 6000 0 1000 0 nl_38:2_alkenone-et nd 0 0 0 0 0 0 nd nd 0 nl_38:2_alkenone-me nd nd 0 0 0 0 nd nd nd nd TOTAL 276690 252500 1582500 1339900 695500 422410 855500 721980 815400 315280
