Advanced technology science mission to study Lake Superior fish launches in Ashland

Advanced technology science mission to study Lake Superior fish launches in Ashland

Blue skies and a stiff breeze marked the launch ceremony for an advanced technology mission designed to improve the accuracy of fish population measurement in the Apostle Islands and beyond. That breeze will be important, as the wind is what will power two uncrewed sailboat-like drones as they sail predetermined patterns across Lake Superior with solar-powered hydroacoustic equipment and nearly two dozen other scientific instruments onboard. The US Geological Survey (USGS) and and the Great Lakes Fishery Commission invited dignitaries and journalists to the launch event on the dock next to...

Unmanned Sailing Vessels to Study Fish Populations in the Apostle Islands

Unmanned Sailing Vessels to Study Fish Populations in the Apostle Islands

They might be the strangest looking sailboats that you’ve ever seen navigating the Apostles, but later this month, two bright orange saildrones, with no sailors onboard, will be traversing Lake Superior, collecting data about fish populations. Two 23-foot-long Uncrewed Surface Vehicles (USVs) are scheduled to launch from Ashland on August 8th, as part of a research project by the US Geological Survey (USGS). These scientific sailboats operate on wind power and solar power. They will use acoustic, or sound technology to gather fish distribution and density data around-the-clock, near Madeline...

Past, present and future of fisheries management in the Apostle Islands

Past, present and future of fisheries management in the Apostle Islands

Fish are an important part of the local culture and fisheries management has faced many challenges over the past 50+ years. Declines in fisheries due to invasive species and over-harvest began in the 1950’s and by the formation of the Apostle Island National Lakeshore in 1970 the fish populations were at historic lows. Fisheries management successfully focused on Lake Trout restoration goals thorough cooperative management of all users in Wisconsin waters of Lake Superior. Current management is focused on monitoring and setting safe harvest limits for fisheries through fisheries management...

Where in the park is Neil? The week 18 answer is South Twin Island

As part of the celebration of the 50th Anniversary of the Apostle Islands National Lakeshore, we’re going on a virtual tour with Neil Howk, a man who has spent decades exploring the islands and teaching people about what makes them special. He knows the islands like the back of his hand. Beaches tend to be some of the most heavily used areas in the Apostle Islands.  The fragile vegetation on these sandscapes cannot survive frequent trampling. Today Neil is taking a close look at efforts to help revegetate the sandscape on this island. At the eighteenth stop on our digital tour, Neil is on...
