Analysis of mesozooplankton from pump samples Dataset Description: <p>Subsets of these data were published in the papers listed in the "Related Resources" section.</p>
<p>Related dataset:<br />
* ScanFish Optical Plankton Counter (OPC) data:&nbsp;https://www.bco-dmo.org/dataset/746081</p> Methods and Sampling: Methodology:
Plankton samples were collected from discrete depths during CTD casts using a high-capacity, diaphragm pump with an intake hose mounted to the CTD Rosette. Subsamples of sample contents were manually counted, identified, and measured in the laboratory
Sampling and analytical procedures:
For each sample, the pump was run for a timed period of nominally 5 min. The flow rate of the pump was usually measured immediately prior to sampling, by recording the time required to fill a barrel of known volume. Samples were preserved and stored in 5% buffered formalin. The laboratory protocol was to separate samples into two size fractions by passing them through large (200 or 500 μm) then small (64 μm) mesh sieves; split, dilute, and sub-sample each size fraction as needed; count and identify all plankters (minimum n = 50) in each subsample; and estimate the length and width of exactly 100 plankters (the first 50 from the large and small fraction, respectively) to the nearest 50 μm using a dissecting microscope. Three replicate small size fractions per sample were processed starting in 2006.
Data column "vol" was calculated as follows:
vol = length(unique(replicate)*aliquot/beaker/2^splits*50/s_per_50l*d_min*60*1e-3
Data column "flag" contains the following codes:
flag 1: length & width were not measured, but estimated from similar samples
flag 2: shallow & deep samples not labeled, but deduced from sample contents
flag 3: depth estimate less accurate than usual (± ~3 m)
flag 4: time estimate less accurate than usual (± ~15 min)
flag 5: pump flow rate estimated by nominal flow rate

Gulf of Mexico - Deepwater Horizon Oil Spill
Grants for Rapid Response Research (RAPID)
The RAPID funding mechanism is used for proposals having a severe urgency with regard to availability of, or access to data, facilities or specialized equipment, including quick-response research on natural or anthropogenic disasters and similar unanticipated events.
GOM - Broader Impacts
The need to understand the impact of this largest oil spill to date on ecosystems and biochemical cycling is self evident. The consequences of the disaster and accompanying clean up measures (e.g. the distribution of dispersants) need to be evaluated to guide further mediating measures and to develop and improve responses to similar disasters in the future. Would it be advantageous if such oil aggregates sink, or should it rather remain suspended? Possibly measures can be developed to enhance sinking or suspension (e.g. addition of ballast minerals) once we understand their current formation and fate. Understanding the particle dynamics following the input of large amounts of oil and dispersants into the water is a prerequisite to develop response strategies for now and in the future.

Plankton samples were collected from discrete depths during CTD casts using a high-capacity, diaphragm pump with an intake hose mounted to the CTD Rosette. Subsamples of sample contents were manually counted, identified, and measured in the laboratory

For each sample, the pump was run for a timed period of nominally 5 min. The flow rate of the pump was usually measured immediately prior to sampling, by recording the time required to fill a barrel of known volume. Samples were preserved and stored in 5% buffered formalin. The laboratory protocol was to separate samples into two size fractions by passing them through large (200 or 500 μm) then small (64 μm) mesh sieves; split, dilute, and sub-sample each size fraction as needed; count and identify all plankters (minimum n = 50) in each subsample; and estimate the length and width of exactly 100 plankters (the first 50 from the large and small fraction, respectively) to the nearest 50 μm using a dissecting microscope.

flag 3: depth estimate less accurate than usual (± ~3 m)
flag 4: time estimate less accurate than usual (± ~15 min)
flag 5: pump flow rate estimated by nominal flow rate
Specified by the Principal Investigator(s)
Data processing:
Nominal sampling time and depth were corrected by analysis of CTD upcast data. CTD pressure sensor measurements at depth were adjusted to compensate for non-zero readings on deck of the research vessel over the course of each cruise. Bottom depth was estimated from filtered CTD altimeter and pressure data. Longitude and latitude were taken from the vessel’s MIDAS system or a separate GPS unit at the time the CTD was turned on. Inconsistent taxonomic identifications (e.g., misspelled or misleading colloquial categories) were corrected by manually creating and automatically applying a lookup table. All data processing was performed using the R language and environment for statistical computing.
BCO-DMO Data Manager Processing Notes:
* added a conventional header with dataset name, PI name, version date
* modified parameter names to conform with BCO-DMO naming conventions
* added ISO Timestamp column
* rounded decimal places of columns. Number of decimal places provided by data contributor.
Data version 1: 2018-09-12 replaced by data version 2: 2018-10-22. Dataset was modified to use unique ctd profile identifiers and remove redundant time/date columns (y,m,d,h,m,s).

Sea-Bird 9 CTD
Sea-Bird 9 CTD
PI Supplied Instrument Name: Sea-Bird 9 CTD Instrument Name: CTD - profiler Instrument Short Name: Instrument Description: The Conductivity, Temperature, Depth (CTD) unit is an integrated instrument package designed to measure the conductivity, temperature, and pressure (depth) of the water column. The instrument is lowered via cable through the water column. It permits scientists to observe the physical properties in real-time via a conducting cable, which is typically connected to a CTD to a deck unit and computer on a ship. The CTD is often configured with additional optional sensors including fluorometers, transmissometers and/or radiometers. It is often combined with a Rosette of water sampling bottles (e.g. Niskin, GO-FLO) for collecting discrete water samples during the cast.
This term applies to profiling CTDs. For fixed CTDs, see https://www.bco-dmo.org/instrument/869934. Community Standard Description: http://vocab.nerc.ac.uk/collection/L05/current/130/
