Description

This dataset includes results from experiments investigating the hydraulic activities of the lugworm, Arenicola marina, in different sediment types. Porewater pressure sensing, time-lapse photography, and planar optode imaging methods were used. MP4 movies and NetCDF files are avialable for download. Each file contains 7.5 h of porewater pressure data and nikon images or oxygen planar optode images.

Quick-look files are MP4 movies (with H264 codec) that incorporate simultaneous visible light and optode imagery and pressure records. The movie files provide a "quick look" of what exactly can be found in the NetCDF files.

Netcdf optode files include optode imagery as time-resolved matrices, and a time series of pressure records. Oxygen images are matrices of percent air saturation values. All times are in unix format (seconds since 1970-01-01). Data are in 2.5 hour blocks.

Netcdf Nikon files include visible light imagery as time-resolved matrices and a time series pressure records. Nikon images are matrices of 24 bit RGB values. All times are in unix format (seconds since 1970-01-01). Data are in 2.5 hour blocks.
