Photo Friday: Cold produces sundog above Lake Superior

By Evan KreagerGreat Lakes Echo This image taken over Lake Superior’s southern shore shows a reflection of light known as a “sundog” on the outer edges of a halo surrounding the sun. Fog is created when cold air moves over water that is much warmer. Because of the cold, this fog often contains tiny ice crystals. The crystals can act as prisms, creating a 22-degree circle of light around the sun known as a “22-degree halo,” according to Earth Science Picture of the Day, which published this image. The picture was taken by Shawn Malone on Jan.

Perfect conditions produce “snow rollers” in Ohio, New York

By Evan KreagerGreat Lakes Echo Everyone has seen images of tumbleweed blowing in the wind. This image shows what it looks like when the wind rolls its own snowballs. These snowballs were created by the wind in a field in Ohio, according to Earth Science Picture of the Day, a service provided by NASA’s Earth Science Division that documents naturally occurring phenomenon that highlight the different processes of the world. If the wind blows strong enough, and snow has just the right packing consistency, then the wind can blow snowballs like these ones, known as “snow rollers.” If the wind changes path, so can the snowballs, leaving tracks in the snow behind. This phenomenon is not unique to Newcomerstown, Ohio, where this photo was taken in late January by Bill Schultz.

Invasive Species: Asian Carp

By Evan KreagerGreat Lakes EchoAsian carp may be one of the better known of the many aquatic invasive species attempting to make their way into the Great Lakes basin. They are one of the five “usual suspects” recognized by The Nature Conservancy in a public awareness campaign. Big head and silver are the most common types of carp, having been spotted in 18 different states, according to The Nature Conservancy. Big head carp can grow up to 60 inches and weigh over 100 pounds. Silver carp are a bit smaller, with a length of about 40 inches and a weight of 60 pounds.

Photo Friday: Ice forms Lake Michigan stringers

 

By Evan KreagerGreat Lakes Echo Ice stringers, the lines of ice that can be seen traveling out across these Lake Michigan waters, are formed when strong winds blow ice off a point of land and into a long, connected string. This photograph produced by astronauts on the International Space Station shows Washington Island off the point of Wisconsin’s Door Peninsula and two smaller adjacent islands. They are joined by ice. When this photo was taken on Feb. 22, strong southwesterly winds blew against their ice-covered shores, according to NASA’s Earth Observatory.

Exhibit preserves artifacts of endangered places

Many scientists predict that as climate change becomes more extreme, dry and coastal regions around the globe will be heavily impacted by drought and rising sea levels. Entire communities could disappear. The art project, ‘A People’s Archive of Sinking and Melting,’ documents these threatened areas.

Landscope: Increasing presence of well pads in Michigan

By Evan KreagerGreat Lakes Echo 

Take a look at this map. Cover the title, key and footer. It looks as if someone had a blank map of Michigan and began splattering paint across it. It’s like a work of art. But when the title of the map is revealed, it becomes obvious that all those pretty colors are actually different types of wells strewn across Michigan’s mitten.

Invasive Species: Round Goby

By Evan KreagerGreat Lakes Echo

The Nature Conservancy has named the round goby one of the five “usual suspects” invading the Great Lakes basin. Round gobies are native to the Black and Caspian seas, but have found their way into the Mississippi River as well as Lake Michigan. These fish have a heightened ability to sense water movement, allowing them to feed in the dark. Round gobies feed on native fish and their eggs, and have a “blood vendetta” against zebra mussels, according The Nature Conservancy. These gobies can grow up to 10 inches in length and somewhat resemble an overgrown tadpole with black, gray or brown skin.

Invasive Species: Eurasian Ruffe

By Evan KreagerGreat Lakes Echo

The Nature Conservancy has named Eurasian Ruffe, a fish native to northern Europe and Asia, as one of the five “usual suspects” in the Great Lakes basin. This fish has invaded northern Lake Michigan and feeds on native fish eggs. It has sharp spines on its fins making it difficult for predators to catch and eat, giving it the nickname, “Dagger Fin.”

Eurasian Ruffe are generally just under a half a foot in length and have an olive or golden-brown color.

Photo Friday: Pitcher’s thistle

Here’s a reminder of Great Lakes beaches in warmer times. This plant is the federally and state-protected Pitcher’s thistle, which is also known as a dune thistle. The photo was taken last summer by habitat restoration specialist Terry Heatlie at Bois Blanc Island in north Lake Huron between Michigan’s Upper and Lower Peninsulas. The Pitcher’s thistle is native exclusively to the Great Lakes region, according to the National Fish and Wildlife Service. It was added to the government’s list of threatened species back in 1988.
