At approximately 9:24 a.m. on Friday, April 19, a University of Maine graduate student was struck by a university vehicle on Long Road at the University of Maine campus in Orono. The student reports that they are at a local hospital with minor injuries.

Emergency services, including the Orono Fire Department, University Volunteer Ambulance Corps, University of Maine Police Department, Orono Police Department and Penobscot County Sheriff’s Office responded to the scene.

The university vehicle involved in the incident was a Chevrolet Express van. It was being operated by a university employee.

Counseling services and support are available for students, faculty or staff who may have been affected. The Counseling Center can be reached at 207-581-1392 and the Dean of Students Office can be reached at 207-581-1406.

The scene has been cleared and Long Road is now accessible. An investigation is being conducted by the University of Maine Police Department with assistance from the Penobscot County Sheriff’s Office Crash Reconstruction Unit.

Spawning stocks of Atlantic cod (Gadus morhua) have disappeared from downeast Maine, but juvenile cod have made regular appearances since at least 2000. The source of these juveniles and their adult grounds is unknown. While previous studies have found a segregation of eastern and western Gulf of Maine cod populations , no one has examined the molecular genetics of the eastern fish to determine the origin of these juveniles. Expanding on a study of the molecular genetics of cod from Jeffrey’s Ledge in the western Gulf of Maine (with the Mount Desert Island Biological Laboratory) Tarbox and Roger Woodman, fisherman and owner of the schooner Alert, conducted a survey of Frenchman Bay in August 2011. The purpose was to detect and trap juvenile cod for genetic analysis, map traditional cod grounds, measure temperature, salinity, pH and dissolved oxygen and conduct sonar transects to detect schools of forage fish. While no cod were found, the researchers were able to collect data to compare Frenchman Bay with productive areas of the western Gulf. Sea Grant funds supported transportation and fuel costs for the sampling trip.

Saving the Oceans film crew and host Carl Safina joined the researchers to film their work for an upcoming PBS documentary.
