To support a long-term NOAA Coral Reef Conservation Program (CRCP) for sustainable management and conservation of coral reef ecosystems, from 25 January - 14 February 2008, marine invertebrate quantitative assessments were conducted, as part of Rapid Ecological Assessments (REA), during the Reef Assessment and Monitoring Program (RAMP) Cruise HI0801 in the Pacific Remote Island Areas. Such cruises are conducted at biennial intervals by the Coral Reef Ecosystem Division (CRED) at the NOAA Pacific Islands Fisheries Science Center (PIFSC). At specific reef sites, marine invertebrate zoologists along with coral and algal biologists entered the water and conducted a fine-scale (~100 m2) and high degree of taxonomic resolution benthic REA survey for coral, algae, and key invertebrate species. Invertebrate surveys were focused on quantifying key non-coral invertebrate species common to the reef habitats, and were conducted using a combination of different survey techniques to quantify the diverse communities. These methods included belt-transect surveys, roving-swim surveys, and quadrat surveys. In belt-transect surveys, quantitative counts of key invertebrates were recorded along two consecutively-placed 25m long and 2m wide belt transects (total area = 100 m2). For any species that cannot be identified in the field, a photograph and a representative specimen, if possible, is collected for later identification. Roving-swim surveys were conducted in the general area with the goal to collect qualitative data for rare, larger, and cryptic organisms, such as Crown of Thorns Starfish and Triton's Trumpet snails which may not be seen during belt-transect surveys, and to survey any additional habitats present at the site, e.g. sand, sea grass, pavement, etc. This was accomplished by swimming a zig-zag pattern that extends roughly 5 m on either side of the two transect lines (total length = 500 m). Quadrat surveys were used to quantify the smaller, more cryptic invertebrates which were sometimes overlooked or too numerous to count during belt-transect surveys. Ten 0.25-m2 quadrats were laid out at 2-m intervals along two of the 25-m transects (total area = 5 m2). For each quadrat the percent cover of sponges, octocorals and zoanthids was recorded, as well as urchins, hermit crabs of the genus Calcinus, trapezid crabs, and coralliophilid snails. In addition, up to 25 cm diameters of all urchin species are measured. Based on data from previous REA surveys, a group of target invertebrate species was chosen for quantitative counts at 5 REA sites at Howland Island in the Pacific Remote Island Areas. The species in the list were chosen because they have been shown to be common components of the reef habitats and they are species that are generally visible (i.e.; non-cryptic) and easily enumerated during the course of a single 50-60 minute SCUBA survey.

NODC Accession 0108155 includes chemical, discrete sample, physical and profile data collected from POLARSTERN in the South Atlantic Ocean from 2010-11-28 to 2011-02-05 and retrieved during cruise ANT_XXVII_2. These data include ALKALINITY, DELTA CARBON-13, DELTA CARBON-14, DISSOLVED INORGANIC CARBON, DISSOLVED OXYGEN, HYDROSTATIC PRESSURE, NITRATE, NITRITE, PHOSPHATE, Potential temperature (theta), SALINITY, SILICATE and WATER TEMPERATURE. The instruments used to collect these data include Alkalinity titrator, CTD, Coulometer for DIC measurement and bottle. These data were collected by Mario Hoppema of Alfred Wegener Institute for Polar and Marine Research as part of the CLIVAR_A12_ANT_XXVII_2 data set. The International CLIVAR Global Ocean Carbon and Repeat Hydrography Program carries out a systematic and global re-occupation of select WOCE/JGOFS hydrographic sections to quantify changes in storage and transport of heat, fresh water, carbon dioxide (CO2), and related parameters.

These data were collected under NSF Grant # ARC-0722448 ("BEST: Impacts of Sea-ice on the Hydrographic Structure, Nutrients, and Mesozooplankton over the Eastern Bering Sea Shelf") to Dr. G.L. Hunt, Jr., University of Washington. The eastern Bering Sea shelf supports productive marine ecosystems with extraordinarily valuable fisheries and subsistence resources, but sub-arctic seas are predicted to be one of the regions most sensitive to future warming of the world oceans. Some of the most direct effects of changing climate will be on the extent, duration and timing of sea-ice over the Bering Sea shelf. Sea-ice controls the timing of the spring phytoplankton bloom, the fate of primary production, water column temperature and salinity, and provides a haul out and molting platform for marine mammals. Thus, the most urgent priority of the Bering Sea Ecosystem Study (BEST) is to examine the role of changing sea-ice conditions on the chemical, physical, and biological characteristics of the ecosystem. The first BEST cruise was scheduled on the USCG Healy in April-May 2007, however, physical observations, water column nutrient chemistry, and zooplankton distribution / abundance were not among the ecosystem components funded in the first call for proposals. Project ARC-0722448 funded by NSF after the first call for BEST proposals filled this gap in chlorophyll collections until the remainder of BEST projects could be assembled in 2008.
