SummaryShipboard observations of marine mammal distribution and habitat are expensive and logistically challenging to collect in Arctic
waters. Port facilities are minimal and access to appropriate vessels for spending extended periods of time at sea is extremely
limited. Autonomous platforms like gliders provide the capability to collect both oceanographic and passive acoustic data for
far longer periods of time (weeks to months) and at significantly reduced costs than traditional shipboard or aerial surveys.
We have developed a system to record, detect, classify, and remotely report Arctic and sub-Arctic marine mammal calls in real
time from Slocum ocean gliders based on the digital acoustic monitoring (DMON) instrument and the low-frequency detection and
classification system (LFDCS). The system was successfully demonstrated for Arctic research during three AOOS-funded studies in
the Chukchi Sea during September 2013 and 2014, 11 July \u2013 8 September 2015, and from 10 July - 4 october 2016. The joint
acoustic-oceanographic data were used to examine the distribution, occurrence, and habitat of marine mammals using in-situ
passive acoustic and oceanographic data collected by the glider, and to demonstrate the near real-time detection and reporting
capability of the system
