Claim 0:
1. A system on a floating device deployed in open sea, the system comprising:
a camera configured to capture images;
an inertial measurement unit (IMU) configured to capture IMU data; and,
at least one processor and at least one memory having stored thereon code that when executed by the at least one processor triggers the camera to capture an image based on the IMU data and predetermined criteria, wherein the predetermined criteria comprises:

z>z_thresh×z_peak

−p_radius<p<p_radius

−r_radius<r<r_radius

where z is a current estimate of the height of the sensor carrying device or float (at, above, or below sea level), z thresh is a percentage of average predicted wave height the device or float needs to be above to allow capture, z peak is a maximum height of the device or float over c seconds (used to approximate height of wave crests), p is pitch, p radius is a pitch radius the device or float needs to be within to allow capture, r is roll, and r radius is a roll radius the device or float needs to be within to allow capture.
