4Hz data from 12 Wire Flyer deployments conducted on R/V Sikuliaq cruise SKQ201701S in the Eastern Tropical North Pacific from January to February 2017

Abstract:

This dataset includes the 4Hz data from 12 Wire Flyer deployments conducted on R/V Sikuliaq cruise SKQ201701S in the Eastern Tropical North Pacific from January to February 2017. Data are from a Seabird 49 Fast-CAT CTD, an Aanderaa Optode 4831F, and a Wet Labs Flbb-2k.

Acquisition Description

Data were collected from Wire Flyer deployments from R/V Sikuliaq cruise SKQ201701S in the Eastern Tropical North Pacific during January and February 2017. These data are reported directly from the sensors or were calculated using the seawater toolbox. The data have not been corrected for any time lags.

Known Problems/Issues:
There is some difference in the fluorometer data between the up and down casts. We are not sure what is causing this just yet. This can be seen as an obvious striping pattern in the profile plots. The oxygen sensor has a time lag of 5-7 seconds. Applying this amount of lag helps align the up and down casts well. The data here are not time shifted.

Processing Description

These data have not been processed to any significant extent. The latitude and longitude positions reported are for the Wire Flyer vehicle, and not the ship. This position was calculated using measurements of the clump weight depth and the wire payout.

BCO-DMO Processing:
- concatenated data from 12 separate files into one dataset;
- created new column "deployment_id" (based on original file name);
- converted date/time field to ISO8601 format.

Aanderaa 4831F (fast-response) oxygen optode

Supplied Name: Aanderaa Optode 4831F

Supplied Description:

Oxygen data is from an Aanderaa Optode 4831F.

Instrument Type

Generic Name: Aanderaa 4831F (fast-response) oxygen optode

Acronym: Aanderaa 4831F

Generic Description:

A stand-alone oxygen optode with integrated temperature sensor, manufactured by Aanderaa. This instrument exploits the physio-chemical principle of dynamic fluorescence quenching to measure absolute oxygen concentration and percent saturation. Depth rating: 300 m, 3000 m or 6000 m; oxygen concentration accuracy of < 8 uM or 5 %, and resolution of < 1 uM; air saturation accuracy of < 5 %, and resolution of 0.4 %; response time (63 %): < 8 s.

Sea-Bird SBE 49 FastCAT CTD Sensor

Supplied Name: Seabird 49 Fast-CAT CTD

Supplied Description:

Temperature, salinity and depth are from a Seabird 49 Fast-CAT CTD.

Instrument Type

Generic Name: Sea-Bird SBE 49 FastCAT CTD Sensor

Acronym: SBE-49

Generic Description:

The SBE 49 FastCAT is a CTD sensor for use in autonomous platforms. It contains a SBE 3P temperature sensor, a SBE 4C conductivity sensor and a strain-gauge pressure sensor as standard. It can operate in autonomus (16 Hz per sec) or polled mode (transmits each sample). The sensor is depth-rated to 350 m (plastic housing) or 7000 m (titanium housing). Accuracy: +/- 0.002 deg C (temperature), +/- 0.0003 S/
