The Government of Canada has announced a massive new investment in a Dalhousie-led international ocean-science collaboration — one that positions Canada to become a global leader in the search for safe and sustainable solutions for harnessing the world’s ocean resources.
The Honourable Scott Brison, President of the Treasury Board, was on campus Tuesday to share the news that the federal government would be committing $93.7 million through its Canada First Research Excellence Fund (CFREF) to support the Ocean Frontier Institute.
The Ocean Frontier Institute (OFI) is a powerful new partnership linking ocean experts from Dal, Memorial University and the University of Prince Edward Island with world-leading national and international collaborators in research, government and industry.

A new paper, published in Science, details the explosion in aquatic animal tracking research over the past 30 years and its impact on discoveries about the movements, migrations, interactions and survival of both common and elusive aquatic species.
The review describes a profound revolution, including over 20 examples of scientific breakthroughs, in global ocean observation science achieved through advancements in acoustic and satellite telemetry—tracking via electronic tags placed on organisms ranging from tiny neonate fish to large whales, which transmit data to fixed or mobile receiver stations or orbiting satellites.
Electronic tags can now weigh less than a penny, can transmit for more than 10 years, and can be attached to almost any species, at any life stage, to collect high-resolution data in four dimensions (2D-horizontal, depth and time).
“The vastness and impenetrability of the ocean has historically limited our ability to acquire and process information on animal movements. Telemetry has significantly enhanced our capacity to predict and plan in the face of climate change and human influence,” said Sara Iverson, scientific director of the Ocean Tracking Network and corresponding author on the paper.
Telemetry data have revealed the often-mysterious migrations of endangered marine animals like leatherback turtles, basking sharks, European eels and Pacific bluefin tuna. These discoveries, and the increasingly sophisticated technology behind them, generate critical knowledge towards conservation recommendations. Tracking studies also pinpoint successes and limitations of current management plans. For example, acoustically tagged reef fish were shown to regularly move outside their Marine Protected Area, putting them at risk.
“In the future, we could be looking at spatially dynamic MPAs, which move annually with predictions of animals’ response to their environments,” said Nigel Hussey, lead author and researcher at the University of Windsor with the Ocean Tracking Network.
Acoustic and satellite telemetry studies are being combined with other biological measurements like genetic analysis or physiological status. These data help determine drivers behind animal behaviour to forecast how anthropogenic and climate changes will affect species and populations.
Aquatic animal movements and migrations transcend geopolitical, economic, and management boundaries. Telemetry studies in the last decade have documented movement over transoceanic scales, to regions unreachable by humans, and into some of the harshest parts of the ocean, providing the groundwork for “next-generation aquatic governance frameworks.”
“The ocean will continue to change,” said Hussey. “Global collaboration—among industry and science sectors, and researchers themselves—is imperative to get ahead of these changes before they catch up to us.”
The Ocean Tracking Network (OTN) is a $168-million research and technology development platform headquartered at Dalhousie University, in Halifax, Nova Scotia. Starting in 2008, OTN began deploying Canadian state of the art acoustic receivers and oceanographic monitoring equipment in key ocean locations and establishing partnerships with a global community of telemetry users. OTN is documenting the movements and survival of aquatic animals carrying electronic tags and how both are influenced by oceanographic conditions.
OTN is funded by the Canada Foundation for Innovation and the Natural Sciences and Engineering Research Council of Canada, with additional support from the Social Sciences and Humanities Research Council of Canada and the Nova Scotia Research and Innovation Trust, as well as international partner contributions. oceantrackingnetwork.org
Says a report of the London Workshop on the Future of the Statistical Sciences (http://bit.ly/londonreport).
"Applying Bayesian spatio-temporal models to fisheries bycatch in the Canadian Arctic" has been accepted for publication in the Canadian Journal of Fisheries and Aquatic Sciences. Great job Aurelie!
"Behavioral attributes of turbine entrainment risk for adult resident fish revealed by acoustic telemetry and state-space modeling" now appears in Animal Biotelemetry. Fantastic Eduardo!
After a successful 4th Annual Ocean Tracking Network Symposium here in Ottawa we are off to Parliament Hill to show off the Wave Glider. Sure to be an interesting afternoon!
Last week I was invited to visit my son's preschool classroom to tell them a little bit about my job. Of course as part of our discussion I went for the tried and true 'how many jelly beans are in this jar?'. Believe it or not all 21 of them made a reasonable guess and the mode of their guesses was actually 100 - the answer! Pretty cool, well at least to a statistician :-)
