In this data release, Cenozoic calcareous nannofossil occurrence charts are provided as Microsoft Excel spreadsheets for 57 cores, wells, or outcrops from the Mid-Atlantic Coastal Plain (Virginia, Maryland, Delaware, and New Jersey) and one core from offshore New Jersey. Samples have been assigned a USGS sample number and are organized by depth below (cores and wells) or height above (outcrops) the land surface. Based on their known stratigraphic position, lithology, and specific calcareous nannofossil species content, each sample, where possible, was assigned to a geologic formation, age, and standard Martini (1971) calcareous nannofossil biostratigraphic zone. Six additional reference files are provided: (1) introductory...

The U.S. Geological Survey recovered 9 piston cores from theNorthwind Ridge in the Canada Basin of the Arctic Ocean from acruise of the USCGC Polar Star during 1988. Preliminaryanalysis of the cores suggests sediments deposited onNorthwind Ridge preserve a detailed record of glacial andinterglacial cycles for the last few hundred-thousand to onemillion years. This report includes quantitative data onforaminifers and selected sediment size-fraction data insamples from Northwind Ridge core PI-88AR P5.

This report includes quantitative data onforaminifers and selected sediment size-fraction data in 98samples from Northwind Ridge core PI-88AR P3, 51 samples fromcore PI-88-AR P7 and 117 samples from core PI-88-AR P9.
In this data release, Cenozoic calcareous nannofossil occurrence charts are provided as Microsoft Excel spreadsheets for 15 cores or outcrops from the Gulf Coastal Plain (Alabama, Mississippi, and Georgia). Samples have been assigned a USGS sample number and are organized by depth below (cores and wells) or height above (outcrops) the land surface. Based on their known stratigraphic position, lithology, and specific calcareous nannofossil species content, each sample, where possible, was assigned to a geologic formation, age, and standard Martini (1971) calcareous nannofossil biostratigraphic zone. Five additional reference files are provided: (1) location information for each core or outcrop, (2) a list of calcareous...
In this data release, Cenozoic calcareous nannofossil occurrence charts are provided as Microsoft Excel spreadsheets for 17 cores from the South Atlantic Coastal Plain (North Carolina, South Carolina, and Georgia) Samples have been assigned a USGS sample number and are organized by depth below the land surface. Based on their known stratigraphic position, lithology, and specific calcareous nannofossil species content, each sample, where possible, was assigned to a geologic formation, age, and standard Martini (1971) calcareous nannofossil biostratigraphic zone. Five additional reference files are provided: (1) location information for each core, well, or outcrop, (2) a list of calcareous nannofossil species found...

This database contains a comprehensive inventory of geologic (coral, rock, and sediment) cores and samples collected, analyzed, published, and/or archived by, or in collaboration with, the U.S. Geological Survey St. Petersburg Coastal and Marine Science Center (USGS SPCMSC). The SPCMSC Core and Sediment Sample Database includes geologic cores and samples collected beginning in the 1970s to present day, from study sites across the world. This database can be accessed through the CoreViewer 3.0 ArcOnline web mapping application, linked below. A copy of the data can also be downloaded from the web mapping application and the metadata is accessible through a link in the header of the application, as well as, through...

Variability in sediment properties with depth and the thickness of individual sedimentary layers are critical determinants of seabed acoustic response. The New England Mud Patch, located south of Cape Cod, is an unusual feature on the U.S. Continental Shelf in that it is composed of fine-grained sediment layers containing a relatively-homogeneous mix of sand, silt, and clay-sized particles bounded by more typical sandy shelf sediments. The unique characteristics and nature of this deposit is due to a derivation of sediments that have been transported to, and deposited in, a basal bowl-shaped depression since the last glacial maximum. Ninety-two piston, vibra-, and gravity cores with a maximum length of 8.2 meters...

The Arctic Ostracode Database provides species census data for about100 species of benthic marine Ostracoda from modern surface and lateQuaternary sediments from various parts of the Arctic Ocean andadjacent seas. Ostracodes are a microfossil group of bivalvedCrustacea that secrete a calcareous shell commonly preserved insediments in the Arctic region. Because many ostracode species haveecological limits controlled by temperature, salinity, oxygen, foodand other factors, they can provide an important tool forpaleoceanographic reconstruction in the Arctic. Some recentapplications of ostracodes to understanding Arctic Ocean historyinclude Briggs (1983), Reimnitz et al. (1983, 1992), McDougall etal. (1986), Clark et...
