glidertools.utils.calc_dive_number

glidertools.utils.calc_dive_number(time, depth, dive_depth_threshold=15)

Determine the glider dive number (based on dive phase)

Parameters:

• time (np.array [datetime64]) – glider time dimension

• depth (np.array [float]) – depth (m) or pressure (dbar) if depth not avail

• dive_depth_threshold ([float]) – minimum dive depth (m or dbar), should be less than your most shallow dive

Returns:

dive_number – the dive number where down dives are x.0 and up dives are x.5

Return type:

np.ndarray [float]
