Woods Hole, Mass. -- Dolphin experts are monitoring and evaluating two dolphins in the Shrewsbury River in east central New Jersey. Local dolphin researchers and officials with the National Marine Fisheries Service (NMFS), the federal agency responsible for marine mammal management, are watching the dolphins to determine whether intervention is necessary.

Two dolphins sighted for the first time in the Shrewsbury River almost two months ago are still there, heightening the level of concern among some experts who fear the mammals might not be able to make it out of the river on their own.

A team of marine mammal experts will attempt today to rescue two dolphins that have been stranded in the Shrewsbury River since early September.
