attribute NC_GLOBAL acquisition_description String At sea, animals were captured for physiological experiments using a 1 m\ndiameter, 150 \\u00b5m (in 2011) or 335 \\u00b5m (in 2012) mesh Reeve net trawl,\nor a 1 m2 MOCNESS tow with 150 \\u00b5m mesh nets. Pteropods were placed in\nfiltered seawater at densities of < 30 individuals liter-1 and acclimated for\nat least 8 hours at 20\\u00b0 C, 15\\u00b0C or 10\\u00b0C in temperature\ncontrolled waterbaths. After acclimation, individuals that were in good\ncondition were put into glass syringe respiration chambers with a known volume\nof 0.2 micron filtered seawater for at least four hours.\n \nIn 2012 on cruise NH1208, an experiment\\u00a0 was conducted to determine\nwhether antibiotics changed the metabolic rate of the pteropods. In this\nexperiment water was treated with 25mg each of Streptomycin and Ampicillin\nliter-1 or without antibiotics.\n \nUnless otherwise explicitly stated, the water contained 25mg each of\nStreptomycin and Ampicillin liter-1, to prevent bacterial growth, and was\nbubbled with certified gas mixes to achieve normal air saturated (21% O2, 380\nppm CO2), high CO2 (21% O2, 800 ppm CO2), low O2 (10% O2, 380 ppm CO2) or low\nO2 high CO2 (10% O2, 800 ppm CO2) conditions. Bubbling of 10% O2 achieved a\nmean initial O2 concentration of 10-13% in low O2 treatments.\n \nDuring all experiments, we simultaneously ran a control syringe (without an\nanimal)\\u00a0 to monitor background respiration of microbes. At the conclusion\nof the experiments, we measured the O2 level by withdrawing a sample of water\nfrom the chamber using a\\u00a0 500 \\u00b5L airtight Hamilton syringe and\ninjected past a Clarke-type O2 electrode (#1302) and meter (#782) in a water-\njacketed injection port (#MC100, Strathkelvin Instruments, North Lanarkshire,\nUnited Kingdom; Marsh and Manahan, 1999). Our resulting O2consumption rates\nare reported in \\u00b5moles g-1 h-1 (wet mass). Notes on carbonate chemistry\nand net profiles are in the cruise report.

attribute NC_GLOBAL instruments_0_description String A Reeve Net is a conventional ring net with a very large acrylic cylindrical cod-end (30 liters) designed to collect fragile gelatinous animals. The net is lowered to a particular depth and then hauled slowly back to the surface (5-10 m/min). Reeve (1981) also described a double net system with no bridle and flotation at the net mouth that is attached to a roller mechanism that rides on a tow wire.\nThe roller system is locked in place by a pressure release device. Once below a set pressure, the roller\nand nets are released and they float slowly up the wire, gently collecting the zooplankton, without being\ninfluenced by the motion of the vessel and associated vertical wire movements.

attribute NC_GLOBAL instruments_1_description String The Multiple Opening/Closing Net and Environmental Sensing System or MOCNESS is a family of net systems based on the Tucker Trawl principle. There are currently 8 different sizes of MOCNESS in existence which are designed for capture of different size ranges of zooplankton and micro-nekton  Each system is designated according to the size of the net mouth opening and in two cases, the number of nets it carries. The original MOCNESS (Wiebe et al, 1976) was a redesigned and improved version of a system described by Frost and McCrone (1974).(from MOCNESS manual)  This designation is used when the specific type of MOCNESS (number and size of nets) was not specified by the contributing investigator.

attribute NC_GLOBAL instruments_2_dataset_instrument_nid String 6116
attribute NC_GLOBAL instruments_2_description String A miniaturized Clark-type dissolved oxygen instrument, including glass micro-sensors with minute tips (diameters ranging from 1 to 800 um). A gold or platinum sensing cathode is polarized against an internal reference and, driven by external partial pressure, oxygen from the environment penetrates through the sensor tip membrane and is reduced at the sensing cathode surface. A picoammeter converts the resulting reduction current to a signal. The size of the signal generated by the electrode is proportional to the flux of oxygen molecules to the cathode.The sensor also includes a polarized guard cathode, which scavenges oxygen in the electrolyte, thus minimizing zero-current and pre-polarization time.With the addition of a meter and a sample chamber, the respiration of a small specimen can be measured.  Example: Strathkelvin Inst. http://www.strathkelvin.com

attribute NC_GLOBAL projects_0_description String Modified version of the NSF award abstract:\nThe impact of ocean acidification on marine ecosystems represents a vital question facing both marine scientists and managers of ocean resources. Thecosome pteropods are a group of calcareous planktonic molluscs widely distributed in coastal and open ocean pelagic ecosystems of the world¡¦s oceans. These animals secrete an aragonite shell, and thus are highly sensitive to ocean acidification due to the water column's changing carbonate chemistry, and particularly the shoaling of the aragonite compensation depth at which seawater becomes corrosive to aragonite. In many regions, however, relatively little is known about the abundance, distribution, vertical migratory behavior, and ecological importance of pteropods. Assessing the likely ecosystem consequences of changes in pteropod dynamics resulting from ocean acidification will require a detailed understanding of pteropod distribution and abundance relative to changing aragonite saturation in the water column.\nThe primary objective of this project is to quantify the distribution, abundance, species composition, shell condition, and vertical migratory behavior of oceanic thecosome pteropods in the northwest Atlantic and northeast Pacific, and correlate these quantities to hydrography and concurrent measurements of carbonate chemistry, including vertical and horizontal distributions of aragonite saturation. In particular, the project will capitalize on present-day variability in the depth distribution of aragonite saturation levels within and between the Atlantic and Pacific Oceans as a \"natural experiment\" to address the hypotheses that pteropod vertical distribution, species composition, and abundance vary as the compensation depth becomes shallower. Secondary objectives are to develop acoustic protocols for the remote quantification of pteropod abundance for future integration into ocean acidification monitoring networks, and to characterize carbonate chemistry and nutrients along portions of two WOCE/CLIVAR Repeat Hydrography transects (A20 in the Atlantic and P17N in the Pacific) to identify decadal-scale changes in the carbonate system. These hypotheses and objectives will be addressed through two cruises along survey transects between 35 and 50 degrees North in the northwest Atlantic and northeast Pacific involving a combination of station-work and underway measurements, and a comprehensive array of instruments, including acoustic, optical, towed net, hydrographic, and carbonate chemistry sensors and sampling systems.\nThis highly inter-disciplinary project, combines expertise in zooplankton ecology, acoustics, and marine chemistry. The proposed work will result in a detailed baseline understanding of variability in the horizontal and vertical distribution, as well as species composition, of thecosome pteropods in the northwest Atlantic and northeast Pacific, making a key contribution to zooplankton ecology generally. In addition, by quantifying the response to current spatial variability within and between the Atlantic and Pacific Oceans, the project will provide important information on the likely response of pteropod distribution to future changes in the vertical distribution of aragonite saturation levels, a necessary component in modeling the impacts of ocean acidification on marine ecosystem function, services, and resources.\nOcean acidification is increasingly appreciated as an urgent societal concern. Thecosome pteropods are key prey for a variety of commercially-exploited fish species, and the improved understanding the PIs seek of pteropod distribution and likely response to changing water column carbonate chemistry will have important implications for our understanding of potential effects of ocean acidification on marine resources.
