Summary

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.
