Marine Geology Data
US Geological Survey BLM/OCS Baltimore Canyon (Mid-Atlantic) Data Set
NGDC Data Set G02882
World Data Center for Geophysics & Marine Geology, Boulder
NOTE: PLEASE CITE ORIGINAL REFERENCE WHEN USING THESE DATA
SUMMARY
This data set contains analytical data from samples acquired from the
Baltimore Canyon (Mid-Atlantic) area of the Outer Continental Shelf,
U.S. east coast, by the U.S. Geological Survey, Office of Marine
Geology, Woods Hole, Mass., 02543, during the first year of
environmental assessment work funded by the Bureau of Land Management
(1 July 1975 - 30 June 1976). The data set contains ten files.
The first file ("station data") contains location and collection
documentation for the subsequent files which contain the various
analytical data. The station data in the first file are keyed to
the contents of the subsequent files (except file 4) by a key
number. The key number merely serves as a link between the station
data and various analytical data to enable the data lines to be kept
shorter than 130 characters, the usual capacity of a line printer.
In many cases, the key number will appear in two or three of the
data files, indicating that several types of analyses were performed
on subsamples of the same prime sample. Similarly, repetition of
a key number within a single file indicates that analyses were
performed on parts of a single prime sample - grain size analyses
at intervals down a single core, for example. The core intervals
or in some cases, sample depth within water columns are included
in the analytical data files.
SEARCHABLE DATA INVENTORY
NGDC/WDC GMG, Boulder archives a wide variety of digital marine geology data collections, paper reports, microfilm, etc. containing sediment and hardrock data. Many of the digital files are available for direct download. Sample-by-sample inventory information for all data, regardless of format available from NGDC are fully searchable through the marine geology inventory (GEOLIN).
