A rugged, whitewater river flowing northward through deep canyons, the New River is among the oldest rivers on the continent. New River Gorge National River in West Virginia encompasses over 70,000 acres of land along the New River, is rich in cultural and natural history, and offers an abundance of scenic and recreational opportunities.
Big Southern Butte is one of two domes rising from a sea of basalt near the center of the eastern Snake River Plain in Idaho. The butte is one of the largest volcanic domes in the world, but at 300,000 years old it is also one of the youngest. Hikers who trek to the 7,550-foot high summit are rewarded with spectacular panoramic views. Photo by Devin Englestead, BLM Upper Snake Wildlife Biologist.
First light at Bosque del Apache National Wildlife Refuge in New Mexico. Established in November 22, 1939, the refuge has provided a critical stopover and wintering spot for thousands of sandhill cranes, geese and other waterfowl for 75 years. Bosque del Apache's sandhill crane population has multiplied from 18 birds in the 1840s to more than 20,000 birds today. Photo by Kim Hang Dessoliers (www.sharetheexperience.org).
DOINews: New Study Looks at Coral Reef Monitoring Protocols
A new paper in Coral Reefs, titled "Calcification rates of the massive coral Siderastrea siderea and crustose coralline algae along the Florida Keys (USA) outer-reef tract", by lead author and SE Climate Science Center funded researcher, Ilsa Kuffner, posts results from a study exploring the systematic measurements of calcification of the coral, Siderastrea siderea. Systematic measurement of coral calcification is important for quantifying potential impacts from ocean acidification, warming, and/or deteriorating water quality on corals. Additionally, ocean acidification is occurring against a background of increases in sea surface temperature (SST) and changes in water quality stemming from land-use change. It is critical to start measuring calcification rates in a systematic way now, particularly at subtropical latitudes where conditions fluctuate seasonally, so that we can understand how changing ocean chemistry and temperatures are affecting calcifying organisms today and predict possible changes in the future.
