47929 ny_jb95o_sedgrabs-meta Data Set Published / External 37225 Benthic Project Completed 2000-05-31 Sediment grab samples were collected using a Shipek grab at pre-determined locations in the harbor. Grain size distributions and organic content were measured and used to assess sediment conditions in New York/New Jersey Harbor and to compare with sediment profile images taken at the same stations. All data were entered into a database, and the database was then used in a Geographic Information System (GIS) to characterize sediment environment in New York/New Jersey Harbor. Original contact information: Contact Org: NOAA Office for Coastal Management Phone: 843-740-1202 Email: coastal.info@noaa.gov The US Army Corps of Engineers (USACE) had a need to develop benthic habitat maps in NY/NJ Harbor. This was critical for developing a plan for dredged material management that was both economically feasible and environmentally sound. The overall objective was to provide background information to plan cost-effective, spatially focused studies for siting dredge material disposal and habitat restoration within the Harbor. These sediment data were useful in supplementing sediment profile data taken concurrently, and they were useful for examining the relationships between sediment organics and species distributions. 10085 none Theme Global Change Master Directory (GCMD) Science Keywords EARTH SCIENCE > BIOSPHERE > ECOSYSTEMS > MARINE ECOSYSTEMS > BENTHIC Theme Global Change Master Directory (GCMD) Science Keywords EARTH SCIENCE > BIOSPHERE > ECOSYSTEMS > MARINE ECOSYSTEMS > COASTAL Theme Global Change Master Directory (GCMD) Science Keywords EARTH SCIENCE > BIOSPHERE > ECOSYSTEMS > MARINE ECOSYSTEMS > ESTUARY Theme ISO 19115 Topic Category boundaries Theme ISO 19115 Topic Category geoscientificInformation Theme ISO 19115 Topic Category location Theme ISO 19115 Topic Category planningCadastre Spatial Global Change Master Directory (GCMD) Location Keywords CONTINENT > NORTH AMERICA > UNITED STATES OF AMERICA > NEW YORK Theme Environmental Monitoring Theme GIS Theme OCM Benthic Habitat Mapping Theme geographic information system Theme sediment Theme sediment grab Theme sediment organics Spatial Bowery Bay Spatial Flushing Bay Spatial Jamaica Bay Spatial New Jersey Spatial New York Spatial New York Harbor Spatial Newark Bay Spatial Northeastern U.

Database Exchange Format (DBF) Values were checked against hard copy data sheets provided by the analysis laboratory. Total organic carbon analyses were repeated for samples where two subsamples differed by more than 10% (e.g., if sediment TOC was 1%, the replicate subsample must have a TOC between 0.9% and 1.1%). Stations were located in the field using a differential Global Positioning System (GPS), and station coordinates, date and time of day were recorded upon arrival at each station. Not relevant to the dataset. All grab data were included in this data layer. All data are believed to be logically consistent.

Army Corps of Engineers 2000-05-31 Discrete 1995-10 Textural analysis and organic content for sediment grabs collected for the NY/NJ Harbor project. | Source Geospatial Form: tabular digital data | Type of Source Media: spreadsheet 1 A Shipek grab (0.04 m2) was used to collect benthic and sediment samples from one-third of the stations, and the grab was operated concurrently with deployment of a sediment profile camera from a different area of the RVOnrust. Two grabs were taken at each of the grab-sampled stations. All sediments collected in the second grab were subsampled and frozen for grain size and total organic content(TOC) analyses. Texture analyses were performed by Tierra Consulting, Inc., Mobile, AL. Each sample was washed with de-ionized water, dried, and weighed. The coarse fraction was separated from the fine fraction (sand/silt) by sieving through U. S. Standard Sieve Mesh No. 230 (62.5 mm).Sediment texture of the coarse fractions was determined at half- phi intervals by passing the sediment through nested sieves on a Ro-Tap apparatus. The weight of the material on each sieve was recorded. A Sedigraph 5000 ET Particle Size Analyzer was used to analyze the fine fraction ( less than 62.5 mm). Sediment texture descriptions followed the Wentworth classification. Total organic carbon (TOC)analyses were done at the USACE Waterways Experiment Station,Vicksburg, MS, using a weight-loss-upon-ignition procedure.Samples collected in the field were stored in a freezer until analysis could be performed. After thoroughly mixing the thawed contents of the bag, two 10-g samples of sediment were removed,dried, weighed, ignited at 500 degrees Celsius to drive off organic material andre-weighed. TOC was assumed to be the weight lost upon ignition and expressed as a percentage. 1996-01-01T00:00:00 NY/NJ Harbor shallow water survey, October 1995 49340 Entity gov.noaa.nmfs.inport:47929 Anne Ball 2017-11-14T12:57:42 SysAdmin InPortAdmin 2023-05-30T18:09:28 2018-04-11 Office for Coastal Management OCM 1002 Public No No 2018-04-11 1 Year 2019-04-11
