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. In 2011 and 2012, the scope of the study area was expanded to include the Hanna Shoal Regional Study Area.
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 chlorophyll and nutrient concentrations of water samples collected in the northeastern Chukchi Sea during the 2008-2012 open water season. Parameters in this data set include the cruise ID, the station the data was collected from; the local date and time of sample collection; the depth of the water where the sample was taken; the depth at which the sample was taken; latitude and longitude of the location at which the sample was collected; the total nitrogen, chlorophyll a , nitrite, nitrate, ammonium, silicate, phosphate and dissolved inorganic nitrogen concentrations in the sample, title of the report the data set supports; the name of the contractor who recorded and analyzed the data; and any additional notes concerning the record.
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
Supplemental_Information:
Edition 3 Updates (March 2014): Incorporated PI edits, added keywords and changed attribute CHLA_MG_L to CHLA_UG_L. Additional Disclaimer of Liability added.
Edition 2 Updates: Metadata was updated to include details about 2011 season, the projection was changed from NAD83 to WGS84, and range domains in attribute metadata were removed.

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.
The TigerSoft application was developed in 2009 to better manage all scientific data collected through the CSESP. TigerSoft consists of three components: TigerObserver, TigerNav, and TigerObserver Server. Under the oversight of a data manager, these three programs worked in concert with predetermined scientific data protocols to integrate scientific observations with vessel navigation to produce standardized data sets. Data sets were backed up regularly and made available to scientists to proof and edit on a nightly basis during the cruises. TigerSoft was used each season for data collection since it's inception in 2009.
After the conclusion of each field season, data managers merged the TigerSoft daily observation databases of each discipline and distributed the data in Excel spreadsheet format to the primary investigators of each discipline. Primary investigators reviewed their data and signed forms acknowledging the completeness and accuracy of the data. If corrections needed to be made to the data, detailed information regarding the corrections and an edited copy of the data was returned to the data manager. Examples of corrections include updated species identification and deletion of an observation event that was made in error.
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.

Horizontal_Positional_Accuracy_Report:
Since 2010, latitude and longitude values were obtained through a Hemisphere VS100 Heading and Positioning Receiver. The horizontal accuracy of the instrument was +/- 0.6 meters.

Methodology_Type: Field and Lab
Methodology_Description:
Chlorophyll and nutrient concentrations were collected from water samples collected at depths of 0, 5, 10, 20, 30 and approximately 40 meters depth using Niskin bottles. Chlorophyll samples were filtered onto a GFF filter and immediately frozen. Chlorophyll was extracted in 6 ml of acetone and read on a Turner Trilogy flourometer. Frozen nutrient samples were measured post-cruise using an Alpkem Rapid Flow Analyzer
