Coastal Marine Mammal Habitat Exploration Using Big Ocean Data

Big Questions Require Big Data

The National Science Foundation-funded Ocean Observatories Initiative (OOI) maintains a series of coastal and oceanic monitoring sites that consists of a multitude of physical and biological sensors. As part of this program, OOI collects continuous data from a cabled array along the continental shelf and slope off Newport, Oregon. Ocean Science Analytics is currently exploring the occurrence of vocally active marine mammal species in relation to coastal ocean parameters during several years of the warm water “blob” anomaly. We are using the open-access bioacoustic analytical software PAMGuard and Python methods and routines acquired during the 2018 Ocean Hack Week to explore this big ocean dataset.

Python is a versatile and powerful programming language that enables efficient analysis of computationally intensive oceanographic datasets. The OOI community provides a set of useful python-based tools and datasets to help get you started with exploration of cabled array, moorings, glider, cruise and other data. 

This open-source software program is an industry-leader in the passive acoustic monitoring (PAM) of marine mammals.  In addition to real-time monitoring, PAMGuard provides a suite of powerful post-processing tools.  We plan to use the LTSA and ViewerMode functionality to assess the presence of vocally active marine mammals.
