Dataset: Images, porewater pressure, O2 data from lab experiments of lugworm Arenicola marina in different sediment types; conducted at Wadden Sea Station Sylt, Germany in 2007 (Infaunal Hydraulics project)

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.
