Dataset: Copepod track data from a set of 4 experiments quantifying the foraging behavior and ingestion by copepods within different distributions of marine snow

Below are the descriptions of the Matlab ".mat" data files in the attached file "MarineSnowLayers_CopepodTracksData.zip".

All Matlab files are named in the following format:

EXPX_TR_CAMYY_Track_ZZ

where "X" will be 1, 2, 3, or 4 corresponding to the Experiment number of the track,
"TR" will be CG (representing control with gradient treatment), CNG (representing control with no gradient treatment), Homogenous (representing homogenous treatment), or Layer (representing layer treatment),
"YY" will be either 01 or 02 representing the camera number, and
"ZZ" will be a number representing the copepod track number.

The total number of tracks varies by treatment and experiment according to the table below:

Exp.              Treatment               Camera         Number of Tracks

Each Matlab file contains the same three vectors depending on the camera:
cop_xloc_cm (for Camera 1) or cop_yloc_cm (for Camera 2)
cop_zloc_cam1_cm (for Camera 1) or cop_zloc_cam2_cm (for Camera 2)
time_cam1 (for Camera 1) or time_cam2 (for Camera 2)

The cop_xloc_cm/cop_yloc_cm provide the horizontal location of the copepod in cm from the edge of the tank (defined as the x direction for Camera 1 and the y direction for Camera 2).

The cop_zloc_camX_cm vectors provide the vertical location of the copepod in cm from the bottom of the tank in Cameras 1 and 2, respectively.

And the time_camX vectors provide the time in seconds since the first copepod appeared in the field of view.

All three of the vectors in each individual Matlab file are the same length and indicate the number of sequential images that the copepod was tracked.
