Western Antarctic Peninsula Bacteria (Mesocosm exp.)
Version 1.2 Publié par SCAR - Microbial Antarctic Resource System le Jan 17, 2019
Amplicon sequencing data of the 16S SSU rRNA marker gene of bacteria in four Mesososm experiments that spanned the spring transitional period (August–December 2013) in surface waters of the Western Antarctic Peninsula (WAP). Each mesocosm consisted of nearshore surface seawater (50 L) incubated in the laboratory for 10 days. Further details in: Luria, C. M., Amaral-Zettler, L. A., Ducklow, H. W., Repeta, D. J., Rhyne, A.

| Description du domaine d'étude / de recherche | Western Antarctic Peninsula |
| Description du design | Mesocosm experiments were conducted in August, September, October, and December 2013 at Palmer Station by filling acid-washed 50 L polycarbonate carboys with seawater from the station’s intake. The filled carboys were divided into two treatments: (1) control (no additions, n = 3) and (2) +DOM (carboys that received diatom exudates; n = 3). An additional f/2 control treatment (uninoculated growth media, n = 3) was included in the October experiment only. The DOC concentration in the f/2 control was not any different than controls without any added DOC. As such, the f/2 control served as an additional no DOC addition control. The mesocosms were incubated for 10 days at 0°C, except in the August experiment when mesocosms were incubated at 3°C. All experiments were conducted under a low-level of continuous light, 1 × 1014 quanta cm-2 s-1, as measured inside the carboys with a hand-held radiometer (Biospherical Instruments, Inc.). |

Méthodes d'échantillonnage
Mesocosms were set up at Palmer Station, Antarctica, using seawater from the station’s intake, located at a depth of 6 m, 16 m from the shore of the station. This source water was monitored during the experimental period (August–December 2013) to determine any changes in environmental parameters that might influence bacterial community responses in mesocosm experiments. Samples for dissolved nutrients (phosphate, silicate, nitrite, and nitrate) and particulate organic carbon and nitrogen (POC and PN) were processed according to Palmer LTER standard protocols
