Humpback whale calls light up the airwaves

On Saturday night, the 5th November, people listening to the live streaming hydrophone deployed off Lime Kiln Point State Park were surprised and thrilled to hear the calls of a humpback drift out over the airwaves. But as I write this post I find myself listening to humpback calls again, this time live -perhaps it is the same whale as last night, perhaps a different one.

Our live hydrophones at Lime Kiln Point State Park drew listeners from around the world as Southern Resident killer whales hung out off the Lighthouse. We listened long after dark as the whales continued to call and echolocate.

Population effects of Navy sonar on marine mammals?

We’re delighted to announce the release of two reports that we’ve produced working with the Office of Naval Research, exploring how the interim Populations Consequences of Disturbance (iPCoD) might be adapted to explore the population level effects of Navy exercises on marine mammal populations. In this study we focused on populations of Blainville’s beaked whales and sperm whales on US Navy ranges in the Bahamas and around Hawai’i.

A whale sized recovery for the humpback whale

This week we saw some really uplifting news in the whale world. The US government announced that they were removing almost all of the world’s humpback whale populations from the endangered species list. To be precise NOAA Fisheries stated in a press release on September 6th that humpback whales in 9 of 14 newly identified distinct populations have recovered enough that they don’t warrant listing under the Endangered Species Act.

Watching polar bears watching you

A new study is published on polar bear behaviour near ice breaker operations.

Today is Arctic Sea Ice Day. When we think of the Arctic the polar bear is one of the first species we think of. It is an iconic Arctic species but one that is threatened by sea ice loss. The Arctic has experienced record lows in sea ice over recent years. This June set yet another record low for Arctic sea ice extent. The National Snow and Ice Data Centre in the United States reported the sea ice to average a mere 10.6 million square kilometers in June. This may sound like a lot but it is the lowest average sea ice extent for the month of June since the Centre’s records began in 1979.
