The Big Chill: What causes dramatic changes in Lake Superior water temperatures?

The Big Chill: What causes dramatic changes in Lake Superior water temperatures?

After a hot, sweaty hike, there’s nothing more refreshing than a dip in the lake at Julian Bay Beach on Stockton Island. If Lake Superior stays calm enough long enough, the shallowest water, warmed by the sun, can be pleasantly refreshing. Wade out farther and you’ll find the significantly colder water just a few feet below the surface. However, if you throw in some wind and waves, the water temperature can and does drop dramatically. On a much larger scale, surface water temperatures in Lake Superior are always changing, as they are in Julian Bay. In late July surface water temperatures on...

Real-time wave information expands for paddlers and boaters in the Apostle Islands

Real-time wave information expands for paddlers and boaters in the Apostle Islands

APOSTLE ISLANDS NATIONAL LAKESHORE, WISCONSIN (Wisconsin Sea Grant News Release)  – The brains behind the SeaCavesWatch.org website have developed a new website that offers real-time wave condition information for the Apostle Islands National Lakeshore in Lake Superior. Before venturing onto the lake, paddlers and boaters should check WISC-Watch, which stands for Water Information for a Safe Coast Watch. The WISC-Watch site provides information from seven spotter buoys recently deployed throughout the islands, plus Chequamegon Bay near Ashland and Siskiwit Bay near Cornucopia. The buoys...

Resiliency and vulnerability of Apostle Islands coastal wetlands

Resiliency and vulnerability of Apostle Islands coastal wetlands

The Apostle Islands National Lakeshore supports several types of coastal and interior wetlands including lagoons, bogs, freshwater estuaries, marshes and peatlands that provide many important ecological functions. We investigated wetland hydrology, geomorphology, vegetation, macro-invertebrates, and fish to identify communities or wetland types that are most at risk of climate-related impacts. The interaction between Lake Superior water levels and hydrologic connectivity between the wetlands and the lake influence how these wetlands will respond to changing conditions. For example, the...

Emerging Water Resource Issues in the Apostle Islands

Emerging Water Resource Issues in the Apostle Islands

Unique among the world’s waters, Lake Superior lays an impressive foundation for our collective experience of the Apostle Islands. The lake is big, omnipresent, and seemingly resistant to change. However, a closer look reveals a variety of emerging issues and threats. High lake levels and increasingly intense storms have caused significant coastal erosion and damage to coastal resources. Historic rainfall events have delivered excess nutrients and sediments to the lake, affecting its clarity and interacting with warming water temperatures to cause unprecedented blooms of harmful algae....

A Retrospective – Research and Resource Management at Apostle Islands NL

A Retrospective – Research and Resource Management at Apostle Islands NL

The Apostle Islands are a homeland, a place of adventure, solace and beauty, afascinating natural laboratory, habitat for diverse plant and animal communities, a refuge for those that are rare, and a place of national significance. Over time there have been many who have worked tirelessly and passionately to learn, understand, and uncover secrets of this “special collection of islands.” During this presentation, I will provide an overview of the history of natural resource management and research at the national lakeshore over the past 5 decades – highlighting changing issues and needs; the...

Where in the park is Neil? The week 7 answer is North Twin Island

Where in the park is Neil? The week 7 answer is North 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. This week, Neil is on one of the least-developed and least-visited islands: North Twin. The island is among the northernmost in the Apostle Islands National Lakeshore. It is located roughly midway between Outer Island to the east and Devils Island to the west. North Twin has no docks, trails, or campsites....
