R/V FARNELLA 90-4
During the second leg of the cruise 67 cores were collected;
20 in the western SeaMARC 1A survey area, 9 along the base of the Florida
Escarpment, and 38 in the area of the eastern survey. A listing of core
locations, depths, and lengths is provided here in two formats: an HTML
page and an Microsoft Excel
Cores were split, described, and sampled at sea except for those that were
stored for future geotechnical analyses. These field descriptions
have been scanned and are included on this CD-ROM. They may be accessed
by clicking the checkmark icon in the column labeled Field Description
from the HTML formatted core listing.
Of the 67 collected cores, 43 of the cores were later described
as part of the post-cruise analysis. These descriptions are also
available from the HTML formatted
page, and may be viewed by clicking the checkmark icon in the column labeled
Summary. Of these 43 cores, parts of 16 were x-rayed.
Where appropriate, the x-rayed section of the core is highlighted in yellow
on the visual summary descriptions. A reduced and enhanced
version of the x-ray is available for viewing by clicking the yellow box
in the legend area of the visual summary. The ehanced and
reduced x-rays are available in 72dpi GIF files, and are stored in
data/cores/xrays. Links to 300dpi unenhanced and unreduced x-rays
are available from the reduced x-ray page. These full-resolution
images are stored in directory: data/cores/x-rays/300dpi.
Samples were taken from 34 of the cores. The sedimentologic
results of the samples have been summarized and are available here in two
HTML formatted page,
and a Microsoft Excel
The mean grain size, in phi units, is shown in red on the visual summaries
to integrate the textural data with the descriptions.
An ArcView shapefile showing the location of the collected
cores is also available. Core attributes available in the file include
core id, latitude, longitude, sample depth and core length. If you
wish to copy the ArcView shape files to disk, please note that you must
copy all the listed files to the same directory. A zip file containing
all the shapefile components is also available.
For cores that have a visual summary available, a hotlink has been created
from the shapefile to the visual summary image. See the Visual
Summary paragraph above for a description of this information.
These images may be viewed by selecting the hyperlink ()
icon from ArcView, then clicking on a specific core location. If
a visual summary is available for that core, the image will be displayed
in a separate window.
