Closed ruxandra-valcu closed 10 months ago

ruxandra-valcu commented 11 months ago

Overview:

This PR introduces one new function, get_attenuation_mask, that provides mask for signal attenuation areas, as ported from the echopy library.

Methodologies:

The methodology employed uses both previously published method defined:

Ryan et al. (2015) ‘Reducing bias due to noise and attenuation in open-ocean echo integration data’, ICES Journal of Marine Science, 72: 2482–2493.
Ariza et al. (2022) 'Acoustic seascape partitioning through functional data analysis', Journal of Biogeography, 00, 1– 15. https://doi.org/10.1111/jbi.14534

Usage:

The functions can be utilized to create single-channel masks for Sv data
