National Ocean Sciences Bowl Wants You!

The Central Gulf Coast Regional Ocean Sciences Bowl: The Hurricane Bowl takes place at the Scott Aquarium in Biloxi, MS on February 22, 2002.  SAME has been a supporter of this competition since 1999 and I am asking for the expertise and knowledge of each member in a new endeavor.  In 1999 CORE introduced the “Team Challenge Question” at the NOSB final competition.  The success of the format at the national competition has caused the national office to implement this at the regional level as well.  The students are encouraged to work as a team, with each team having the opportunity to win up to 20 points per question. Each 24 regional sites of NOSB have been asked to provide 15 team challenge questions for their competition by the end of October. If you are interested and needing more information please contact Becky Espey at rebecca.espey@usm.edu or (228) 374-5550.

Tips from the Bridge
By: Lisa Ayers Lawrence

What do Steller sea lions, snowflakes, and amphipods have in common? They are the latest topics featured in the Bridge’s Data Tips of the Month, activities that will challenge your students with scientific data and critical thinking exercises. Here’s a quick look at the some of the science and issues surrounding these three topics. For the complete classroom activity, visit the Bridge’s Data Tip Archives.

A Stellar Animal - December 2001

Steller sea lions, the largest of the eared seals, are found along the north Pacific Rim from California to Japan. These sea lions are divided into two distinct stocks that are split at 144° W longitude. These two stocks differ not only genetically but also in the stability of their population. Both groups experienced a dramatic drop in numbers in the 1970s and were provided federal protection in 1972 with the Marine Mammal Protection Act. The eastern stock’s situation has improved, but the stock west of 144° W longitude continues to decline despite being designated as a threatened species in 1990 and as an endangered species since 1997. Is the driving factor competition with commercial fisheries for food, as many believe, or is there more to the story?

Winder Wonderland - January 2002

Snow, to those in the snow belt states, may seem like no day at the beach, but in reality it's far closer than you may think. In fact, that knee-deep snow that upstate New Yorkers trudged through last Christmas was, not so long ago, ocean water in which beach lovers were wading. All of the earth's water is directly connected through the water cycle. Learn some of the water chemistry behind snow, and then take a look at this season’s snowfall.

More Than Mud - February 2002

When thinking of benthic habitats, sand, mud and a few worms probably come to mind. But there are many different types of benthic habitats and organisms, from a complex of mud tunnels housing worms and clams to oyster reefs where invertebrates and fish hide in nooks and crannies. Benthic communities are vital to the ecosystem at large, supplying food and habitat for many organisms and improving water quality through their filter feeders. But benthic communities are also one of the aquatic areas most vulnerable to human-induced problems, especially eutrophication and contamination. Learn how scientists use amphipods, a common Chesapeake Bay benthic organism, as an indicator species to help identify polluted sediments.
