Plankton Imager (Pi-10) data collected during RV Cefas Endeavour surveys. Data
are images, separated by ten minute bins, and may be either unzipped, or
zipped as tar files for that ten minute bin (zipping is a setting that can be
turned on/off by the plankton imager acquisition software). Each image is
directly named with the instrument ID, datetime and GPS data are embedded in
the file metadata EXIF as decimal latitude longitude. These data provide an
overview of where, when and how many images were captured by the plankton
imager. Each row represents a 10-minute bin of images. The raw image data are
stored on azure. The ‘BLOB’ column in the data indicates which folder within
the azure container the data are stored. The HITS column indicates the number
of images within that ten-minute bin and the MISSES column indicates the
number of images not stored (e.g. due to date rate). The MISSES are needed to
resolve abundance data in much the same way as splitting a physical plankton
sample. Note, older data on an earlier prototype are available on request.
The deployment of the Pi-10 is continuous and these data are updated every 3
months.
