Popis

Interactions between bacteria and species of harmful and/or toxic algae are potentially important factors affecting both the population dynamics and toxicity of these algae. Recent reports of bacteria lethal to certain harmful algal bloom (HAB) species, coupled with a rapidly evolving interest in attempting to minimize the adverse effects of HABs through various prevention, control, and mitigation strategies, has focused attention on defining the role of algicidal bacteria in bloom termination. The aim of the present study was to determine if algicidal bacteria active against Karenia brevis, a dinoflagellate responsible for frequent and protracted red tides in the Gulf of Mexico, are present in the waters of the west Florida shelf. To date we have detected one algicidal bacterium from samples obtained during ECOHAB-Florida cruises and we are continuing this effort. A taxon-specific 16S rRNA probe was developed for a previously isolated algicidal strain, 41-DBG2, and we have begun to screen water samples for its presence using fluorescent in-situ hybridization. In addition, we have employed denaturing gradient gel electrophoresis (DGGE) to characterize the diversity of the ambient microbial assemblages and to visualize the band characteristic of strain 41-DBG2. This band can then be analyzed further by excising and sequencing. Our screening results to date have yielded negative results on all but one of the field samples tested, which was positive with the rRNA probe. These largely negative findings may not be unexpected due to the marked temporal and spatial separation of the original algicidal bacterial isolation and the water samples being screened. Future efforts will focus on isolating algicidal bacteria from the same bloom event as the samples for screening are obtained, thereby increasing the likelihood of detecting algicidal strains and permitting a more effective analysis of their population dynamics. Purpose: This project dealing with the potential role of algicidal bacteria in regulating K. brevis bloom dynamics is a targeted ECOHAB proposal, the field portion of which is being conducted through a collaborative working relationship with the ECOHAB-Florida regional project. The present dataset reflects results from analyses of samples collected during the ECOHAB-Florida process cruises identified below. The primary use of these samples has been two-fold: first to screen water samples for the presence of a previously identified algicidal bacterium, strain 41-DBG2, using fluorescent in-situ hybridization of a taxon-specific rRNA probe as well as analysis by denaturing gradient gel electrophoresis (DGGE); and, second, to continue attempts at isolating and identifying algicidal bacteria indigenous to the waters of the west Florida shelf.

Popis

Canada geese use four divisions of the Mark Twin NWR: Louisa, Delair, Cannon, and Calhoun. There was a shortage of cultivated crops, corn and soybeans, on all refuge units except the Delair which had crops approaching normal. Lack of food had little effect on Canada goose populations as three of the four units had significantly greater use than in 1968 when food supplies were abundant to the point of being surplus. The specific behavior of Canada geese on each division is outlined in this report.

The National Oceanic and Atmospheric Administration (NOAA) has the statutory mandate to collect hydrographic data in support of nautical chart compilation for safe navigation and to provide background data for engineers, scientific, and other commercial and industrial activities. Hydrographic survey data primarily consist of water depths, but may also include features (e.g. rocks, wrecks), navigation aids, shoreline identification, and bottom type information. NOAA is responsible for archiving and distributing the source data as described in this metadata record.

Popis

Marine bird sighting and other data were collected from platforms from 28 May 1978 to 09 September 1978. Data were collected by the University of California (UC) as part of the Outer Continental Shelf Environmental Assessment Program (OCSEAP). Data were processed by NODC to the NODC F034 standard Marine Bird Land format. Full format description is available from NODC at www.nodc.noaa.gov/. An analog file for this accession is available from NODC user services. The F034 format contains data from field observations of marine birds made along land survey tracks. These data are collected to provide information on population density and distribution and breeding locales. The contents and structure of data type file are similar to Marine Bird Sighting, Aircraft Census (F033), although the transect distance of land surveys will normally be shorter than that of ship and aircraft surveys. In this data type the investigator defines the lateral dimension of survey distance unit (a specified number of whole meters). Start and end position, date and elapsed time, and number of distance units are reported for each survey. Environmental information may include meteorological and adjacent sea surface conditions, distance to nearest shoreline, ice characteristics, and debris, including oil slicks. Species data may include age, sex, color, plumage, number of individuals, flight direction, behavior, and food source association. Any number of species may be reported within one observation time span.

Popis

To support a long-term NOAA Coral Reef Conservation Program (CRCP) for sustainable management and conservation of coral reef ecosystems, from 5 April - 14 April 2009, line point intercept (LPI) surveys of benthic parameter assessments were conducted, as a part of Rapid Ecological Assessments (REA), during the Pacific Reef Assessment and Monitoring Program (RAMP) Cruise HI0902 in the Marianas Archipelago at biennial intervals by the Coral Reef Ecosystem Division (CRED) at the NOAA Pacific Islands Fisheries Science Center (PIFSC). During the cruise, 25 REA sites were surveyed at Guam Island in the Marianas Archipelago. At the specific REA sites, coral biologists along with algal biologists, marine invertebrate zoologist, and fish biologists entered the water and conducted a fine-scale (~300 m2) and high degree of taxonomic resolution REA survey to assess and monitor species composition, abundance, percent cover, size distribution, diversity, and general health of fish, corals, macro-invertebrates, and algae in shallow-water (< 35 m) habitats. As a part of REA surveys, the line point intercept surveys were used to quantitatively assess average percent live coral cover and other benthic substrates at REA sites. The surveys were conducted along two consecutively-placed 25m transect lines by a coral biologist. All benthic elements falling directly underneath the transect line at 20-cm to 50-cm intervals were recorded as one of nine benthic categories: live coral, dead coral, carbonate pavement, encrusting coralline algae, macroalgae, coral rubble, sand, rock, and other benthic sessile invertebrates. All living benthic elements (e.g., coral, algae, and other invertebrates) were identified to the lowest taxonomic level possible. These data provide the basis for computing quantitative estimates of percent live coral cover, as well as percent cover of the different benthic constituents.

Popis

Temperature profile data were collected using bathythermograph (BT/XBT) casts from YAMASHIN MARU in the Pacific Ocean from September 08, 1976 to September 12, 1976. Data were submitted by Scripps Institution of Oceanography as part of the Thermal Structure Monitoring Program in the Pacific (TRANSPAC) project. Data were processed by NODC to the NODC standard Universal Bathythermograph Output (UBT) format. Full BT descriptions are available at http://www.nodc.noaa.gov/General/NODC-Archive/bt.html. The UBT format contains temperature-depth profile data obtained using expendable bathythermograph (XBT) instruments. Cruise information, position, date and time were reported for each observation. The data record was comprised of pairs of temperature-depth values. Unlike the MBT Data File, in which temperature values were recorded at uniform 5 m intervals, the XBT data files contained temperature values at non-uniform depths. These depths were recorded at the minimum number of points (''inflection points'') required to accurately define the temperature curve. Standard XBTs can obtain profiles to depths of either 450 or 760 m. With special instruments, measurements can be obtained to 1830 m.
