Abstract

This dataset includes ECOpuck fluorometer 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 were collected from an ECOpuck fluorometer on Wire Flyer deployments from R/V Sikuliaq cruise SKQ201701S in the Eastern Tropical North Pacific during January and February 2017. The data have not been corrected for any time lags. The Chl and turbidity are from a Wet Labs Flbb-2k (470/695 nm Chl-a and 700nm turbidity).

The Wire Flyer position was calculated using measurements of the clump weight depth and the wire payout. The layback distance is the Flyer's distance behind the ship. The raw count values were converted with the following coefficients:

self.turb_darkcount=50

self.turb_scalefactor=0.0747

self.chloro_darkcount=41.

self.chloro_scalefactor=0.0072

self.lcm_msg.turb = self.turb_scalefactor * (turb_data - self.turb_darkcount)

self.lcm_msg.chl = self.chloro_scalefactor * (chloro_data - self.chloro_darkcount)

Known Problems/Issues:
There is an asymmetry between the up and down directions, likely due to the flow over the sensor. We have not yet determined a correction for this.
