Scientific sampling event log from R/V Knorr cruise KN207-01 in the southern tip of Nova Scotia to Bermuda in 2012 (SargassoSeaLipids project)

Expand/Collapse All

Description

The science party maintained a digital event log, recording all instrument deployments and significant events during the KN207-01 cruise. Post-cruise time and position corrections have been made (refer to comments column).

Methods & Sampling

The event log was created using the Rolling Deck to Repository (R2R) event log application (ELOG). The log includes a record of all scientific sampling events from the cruise. In addition to event identification numbers unique for the cruise, the scientific sampling event log includes date and time (GMT), position (latitude and longitude), station and cast identifier as appropriate to the sampling event, sampling instrument name (e.g. CTD, Net_Trap, McLanePump), name of person responsible for the sampling event, and a comment field to record additional information. See more information about the R2R event log.

Data Processing Description

BCO-DMO made the following modifications to the data display: Parameter names were converted to lowercase and/or to standard BCO-DMO naming conventions; values of 'NaN' and blanks were replaced with 'nd' to indicate 'no data'; the original 'dateTimeUTC' field was separated into two fields (date_utc and time_utc).

BCO-DMO made the following corrections to the data:
Removed several duplicate entries.
Corrected cast number of event 20120429.1002, from 50 to 51.
Corrected time, lat, lon, and depth for events with comments stating the event was recorded late (see comments column).
Events were added for the deployment of CTD casts 23, 56, and 57.
Corrected time, lat, lon, and depth of deployments of CTD casts 36, 40, 47, and 69 to match the CTD cast data.
