The science party maintained a digital event log, recording all instrument deployments and significant events during the KN210-04 cruise.
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. CTD911, planktonNetTow, 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: http://www.rvdata.us/about/eventlog
Date/time and lat/lon corrections, including those indicated in the comment column, have been made:
- First pass at date/time & position corrections made using script by C. Sellers;
- Additional date/time corrections made by E. Kujawinski, K. Longnecker, & C. Breier;
- Additional position corrections made by S. Rauch.
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', 'N/A', and blanks were replaced with 'nd' to indicate 'no data;
- commas in the comment field were replaced with semi-colons;
- the original dateTimeUTC field was separated into two columns: date_utc and time_utc.
|event||Unique ID number for the event; date-time string does NOT necessarily equal the date-time that the event actually occurred. Value serves a unique identifier only.||dimensionless|
|date_utc||Date (UTC) when the event occurred. Created from original dateTimeUTC field in YYYYmmdd format.||unitless|
|time_utc||Time (UTC) when the event occurred; in hours and minutes (0000 to 2359). Created from original dateTimeUTC field.||HHMM|
|instrument||Name of instrument.||dimensionless|
|action||Activity performed with the instrument.||dimensionless|
|station||Identification number of the sampling station.||dimensionless|
|cast||Consecutive cast number for the instrument.||dimensionless|
|lat||Latitude in decimal degrees at the time the event occurred. North = positive.||decimal degrees|
|lon||Longitude in decimal degrees at the time the event occurred. East = positive.||decimal degrees|
|seafloor||Depth of the water.||meters|
|author||Name of person that recorded the event.||dimensionless|
|comment||Comment entered about the sampling event; free-text.||dimensionless|

Western Atlantic cruise started at Montevideo, Uruguay and ended at Bridgetown, Barbados. Science Objectives: 1. Characterize deep ocean dissolved organic matter in water masses of western Atlantic Ocean. 2. Characterize microbial community at selected stations and at selected depths. 3. Characterize metabolic capabilities of surface, mesopelagic and bathypelagic microbial consortia vis-a-vis the degradation of organic matter from each zone. 4. Examine metabolic and phylogenetic links between microbes in different marine zones (surface, meso-pelagic and bathypelagic depths). Science Activities: 1. Collection of discrete water samples by Niskin-bottles. 2. Collection of microbial communities from these water samples, by in-situ pumping, or by net-traps and net-tows. 3. Incubation experiments in lab and on deck. 4. Underway mass spectrometry and flow cytometry, from seawater intake. More information is available from the WHOI Cruise Planning Synopsis. Additional cruise information and original data are available from the NSF R2R Data Catalog.
