Abstract:

This data set was collected as part of the Chukchi Sea Environmental Studies Program (CSESP), a multi-year, interdisciplinary ecological study focused on areas in outer continental shelf oil and gas leases in the northeastern Chukchi Sea. In 2008 when the program began, two 30 x 30 nautical mile study area boxes were developed around areas of interest to ConocoPhillips and Shell. The ConocoPhillips study area (named Klondike), and the Shell study area (named Burger) became the focus of data collection. Data were collected from these two study areas again in 2009. Then, in 2010, Statoil joined the program, and a third study area, Statoil, was created and sampled as well as Klondike and Burger.
The CSESP interdisciplinary studies include acoustic monitoring, baseline chemistry, benthic ecology, chemical oceanography, fisheries ecology, marine mammal ecology, physical oceanography, plankton ecology and nutrients, and seabird ecology.
This data set contains the results of sediment grain analyses of surface and core sediment samples gathered from the northeastern Chukchi Sea during the open water season of 2008. Data parameters include the sample ID; whether the sample was a surficial or a sediment core; the interval of the core sample in centimeters; the percentages of gravel, sand, silt, and clay found in the sample; the name of the contractor who recorded and analyzed the data; the title of the annual report the data set supports; and any additional notes concerning the sample. Related data sets entitled Sediment Core Sample Collection, NE Chukchi Sea, 2008 and Surface Sediment Sample Collection, NE Chukchi Sea, 2008 contain sample collection information.

Purpose:

The objectives of the Chukchi Sea Environmental Baseline Studies Program are: 1. To provide data for pre-exploration and development-related activities 2. To provide data for permit applications 3. To provide input to planning of future operations and associated mitigation 4. To provide additional baseline data that can be used to assess and measure the potential environmental effects of offshore oil and gas exploration and development in the northeastern Chukchi Sea

Attribute_Accuracy_Report:

CSESP Attribute Accuracy Overview When the program began in 2008, scientists collected and stored their data through a variety of methods. Vessel data were collected by individual software packages and backed up as part of the regular computer backups, which may or may not have coincided with backups conducted by the scientists. Each scientist had his or her own method for recording and storing at sea observations and data; some of these methods included paper copies.

Logical_Consistency_Report:

Each year the primary investigators spent approximately nine months analyzing their data and then produced a discipline specific annual report for CSESP and a final data set. The final data had to adhere to a predetermined data protocol and pass through a data validation tool in order to be accepted by the data manager. Data that did not pass validation were returned to the primary investigators to be corrected and resubmitted for validation.
