Abstract:
In the past decade, much progress has been made in real-time passive acoustic monitoring of marine mammal occurrence and distribution from autonomous platforms (e.g., gliders, floats, buoys), but current systems focus primarily on a single call type produced by a single species, often from a single location. A hardware and software system was developed to detect, classify, and report 14 call types produced by 4 species of baleen whales in real time from ocean gliders. During a 3-week deployment in the central Gulf of Maine in late November and early December 2012, two gliders reported over 25,000 acoustic detections attributed to fin, humpback, sei, and right whales. The overall false detection rate for individual calls was 14%, and for right, humpback, and fin whales, false predictions of occurrence during 15-minute reporting periods were 5% or less. Transmitted pitch tracks – compact representations of sounds – allowed unambiguous identification of both humpback and fin whale song. Of the 10 cases when whales were sighted during aerial or shipboard surveys and a glider was within 20 km of the sighting location, 9 were accompanied by real-time acoustic detections of the same species by the glider within ±12 hours of the sighting time.

*The Sixth International Sirenian Symposium*
The Sixth International Sirenian Symposium will be held on Saturday,
December 7, 2013 in conjunction with the 20th Biennial Conference on the
Biology of Marine Mammals in Dunedin, New Zealand. This symposium will be
kindly sponsored by the Secretariat of the Dugong MOU*, Convention on
Migratory Species Office - Abu Dhabi.
The aim of this full-day symposium, in collaboration with the IUCN
Sirenian Specialists Group, is to foster communication between researchers,
managers, and policy makers. Scientists and managers representing countries
from all over the globe are invited to present new information on Sirenian
conservation and management, stranding response and medical assessment,
monitoring applications, and general biology and research. A special
session will be devoted to Dugong conservation efforts in the Indo-Pacific.
The symposium will include presentations, a poster session, and a Q & A
session. Sirenian items will be available for purchase to raise funds for
future student travel scholarships.
The cost of this workshop is $10.00. Space is limited, so please register

If you would like to submit a presentation or poster please send an
electronic copy of your abstract (300 word limit) to Nicole Adimey (*

We are pleased to announce the publishing of a new book:
Fur Seals and Sea Lions
AUSTRALIAN NATURAL HISTORY SERIES, CSIRO Publishing
by Roger Kirkwood and Simon Goldsworthy
This book outlines the comparative evolutionary ecology, biology, life-history, behaviour, conservation status, threats, history of human interactions and latest research on the three species of otariids that live in the waters of southern Australia: the Australian fur seal, New Zealand fur seal and Australian sea lion. It also includes brief descriptions of Antarctic and Subantarctic seals that occupy the Antarctic pack-ice and remote Australian
territories of Macquarie Island and Heard Island.
The book summarises the enormous amount of new scientific information from studies in the past 10 years, and provides full descriptions of the species and their biology. This book is presented in an easy to read format for general public, students and researchers who want to learn a bit more about seals. It includes 17 pages of colour photos plus many b & w images, graphs and figures. A must for all those interested in marine wildlife.
Fur Seals and Sea Lions can be ordered online: http://www.publish.csiro.au/pid/6491.htm
AUS$39.95
Cheers, Roger Kirkwood and Simon Goldsworthy
