Ship Name

The Ship Name refers to the ship that took the core(s). When choosing a ship, simply click on the pull-down window and select the ship you wish to include in your search. Note: Select "LAND DRILL" if you wish to search for drilling projects such as (DVDP, ETV, etc). If you want to include all available ships (and drilling projects), choose ALL SHIPS.

Cruise Name

The Cruise Name refers to the unique identifier given to a particular cruise.

USNS Eltanin cruises begin with ELT followed by a two digit number ranging from 01-55. The numbers refer to consecutive cruise numbers and not to a particular year.

ARA Islas Orcadas cruises begin with the identifier IO followed by a four-digit number that refers to the cruise number of a particular year (e.g. IO0775 refers to cruise 7 in 1975).

USCGC Glacier cruises have identifiers such as DF (Deep Freeze), IWSOE (International Weddell Sea Oceanographic Expedition), and GL (Glacier). Each identifier is followed by a two-digit number referring to the year of the cruise (e.g., DF80 refers to the Deep Freeze cruise that took place in 1980).

R/V Polar Duke cruises have the identifier PD followed by numbers referring to the year and cruise number of the particular year (e.g., PD92-II refers to the second Polar Duke cruise of 1992). Note the the cruise number is given as a Roman numeral.

R/V Nathaniel B. Palmer cruises have the identifier NBP followed by numbers referring to the year and cruise number of the particular year (e.g., NBP93-08 refers to the eighth Nathaniel B. Palmer cruise of 1993).

Drilling projects have only an acronym as an identifier (e.g., CIROS, DVDP, ETV, etc.).

CORE IDENTIFICATION

Core Identification refers to the unique identifier given to a particular core. Note that numbers between 1 and 9 must be written as 01, 02, 03, etc.

Core Type

Core Type is the type of device used to retrieve the core. All the device types in this category are shown in the Core Type pull-down window in the search menu.

Latitude

Latitude is a numeric field. Northern latitudes range from 0 to 90 and southern latitudes range from 0 to -90. The default value will search the entire range (90 to -90). The smaller value of the range entered must be entered first. For example, if you are searching from 50S to 10S, then you would have "-50" in the From field and "-10" in the To field.

Longitude

Longitude is a numeric field with a range from -180 to 180. Western values are denoted with a negative sign. The default value will search the entire range from -180 to 180. For searches not crossing the International Dateline, the database is simply searched from lowest value (most Western value) to the highest value (most eastern value). These ranges, like Latitude, must have the smaller value in the From field. For example, to search from 170W to 130E (not crossing the International Dateline) you would enter "-170" in the From field and "130" in the To field. If your search does cross the International Dateline, you must mark the check box.

Water Depth

The Water Depth range is a numeric range (in meters below sea level). The default range is sea level (i.e., 0 m) to the deepest core stored in the database.

Core Length

The Core Length is a numeric field. The default range for this category is zero meters to the longest core stored in the facility. For deep-sea cores the values are in centimeters and for drill cores the values are in meters.

Top Interval

The Top Interval is a numeric field that indicates the depth from the top of the core to the top of a sample in a core. For deep-sea cores (i.e., Eltanin, Glacier, Polar Duke cores) the number is given in centimeters below the top of the core. For drill cores (i.e., DVDP, CIROS, ETV) the number is given in meters below the top of the core.

Bottom Interval

The Bottom Interval is a numeric field that indicates the depth from the top of the core to the bottom of a sample in a core. For deep-sea cores (i.e., Eltanin, Glacier, Polar Duke cores) the number is given in centimeters below the top of the core. For drill cores (i.e., DVDP, CIROS, ETV, CRP) the number is given in meters below the top of the core.

Volume

The Volume field indicates the size of a sample. Generally, the Volume field for deep-sea cores (i.e., Eltanin, Polar Duke cores etc.) is given in cubic centimeters. The Volume field for drill cores (i.e., DVDP, ETV, etc.) is given in grams. In some instances, the Volume field for drill cores is listed as a volume ratio of the whole core (e.g, 1/4 core).

Investigator Name

The Investigator Name is the last name of the person who has taken the sample.

Institution Name

The Institution Name is the investigator's institution at the time of sampling. Please use the complete name of the institution and not an abbreviation (i.e. Florida State University and not FSU).

Date Range

The Date Range specifies the time range to narrow your search. This is a date field. Examples of acceptable dates are: 1/1/78, 1/1/1978.
