Row Type Variable Name Attribute Name Data Type Value
attribute NC_GLOBAL access_formats String .htmlTable,.csv,.json,.mat,.nc,.tsv
attribute NC_GLOBAL acquisition_description String From Archer et al. (2018): The mesocosm experiment was conducted in Gando Bay,
on the east coast of Gran Canaria (27\u00b0 55' 41\" N, 15\u00b0 21' 55\" W)
in the subtropical North Atlantic. Sample processing, analysis and further
experiments were conducted in the laboratories of Plataforma Oce\u00e1nica de
Canarias (PLOCAN), Gran Canaria. The full experiment took place from 23rd
September to 25th November 2014. The design and deployment of the Kiel Off-
Shore Mesocosms for future Ocean Simulations (KOSMOS) facility has previously
been described in detail (Riebesell et al., 2013).

Sampling and analytical procedures: The experimental set-up and sampling of
the mesocosms is described in Taucher et al. (2017).

Procedures for the analysis of reduced sulfur compounds was based on purge-
and-cryotrap approaches linked to a gas chromatograph with either flame FPD or
mass spectrometric detector and is described in Archer et al. (2018).

Quantification of dissolved DMSO [DMSOd] closely followed the protocol of del
Valle et al. (2007) and is reported in Archer et al. (2018).

Additional data from the experiment has been deposited on the PANGEA database:

attribute NC_GLOBAL projects_0_description String NSF Award Abstract:
To date, investigations into the biogeochemical consequences of predicted increases in pCO2 and reduced pH in the oceans (ocean acidification, OA) over the next century have largely focused on the production and fate of carbon. Considerably less is known about how OA will influence other biogeochemical cycles or the exchange of reactive trace gases between ocean and atmosphere. Variations in trace gas exchange will alter atmospheric chemistry, including aerosol formation and growth, and potentially feedback on climate change.
In this project, a research team at the Bigelow Laboratory for Ocean Sciences will study the influence of OA on the biological processes that govern the concentrations and hence emission, of dimethyl sulfide (DMS) in the surface oceans. The team will study OA effects on the DMS-cycle in three natural-water mesocosm experiments designed to encompass natural community responses to predicted changes in pCO2 of varying degrees. They will exploit the opportunity to participate in a major experiment in sub-tropical oceanic waters involving the deployment of nine large scale (~60 m3) free floating, pelagic mesocosms, as part of the German-funded BIOACID Program. Two replicate experiments conducted using the new mesocosm facilities at Bigelow will further expand the environmental range of DMS-OA studies. Through a combination of standard analytical approaches, recently developed cutting-edge tracer approaches to determine process rates, as well as the underlying organism diversity and genetic response of microbes involved with biogenic sulfur cycling, they will determine how altered pH influences key biological pathways governing DMS concentrations and the organisms responsible during the experiments.
Broader Impacts: The information generated will be used to inform on-going development of global ocean-atmosphere coupled models, able to examine the influence of ocean acidification on climate change. The information will also be used to further develop physiology-based mechanistic approaches to biogeochemical ecosystem models. A Postdoctoral Research Scientist will be trained in the experimental approaches, will gain modeling experience by working with European scientists, and will develop international and US collaborations, with a common aim to increase our understanding of ocean acidification on ecosystem function. Four undergraduates, two interns and two REU-students, will gain valuable experience by participating in the Bigelow experiments. An additional undergraduate with a mathematical background will be mentored in and participate in the interpretation and modeling aspects. Extensive outreach to K-12 students and teachers as well as the general public will be pursued as part of established Bigelow programs in which all PIs will participate (BLOOM, Cafe Scientifique). Joint programs with Colby College (Changing Oceans semester) and Island Institute will reach undergraduates and Maine island K-8 schools, respectively.
