Data suggests that water vessel collisions with marine life remains one of the most frequent contributors to the premature deaths of critically endangered animals, like the right whale, the blue whale, and manatees. This data comes, in large part, from the National Oceanic and Atmospheric Administration's (NOAA) Ship Strike Reduction Strategy, which tallies private, commercial, and military ship reports, stranded or beached marine animal sightings, and routine updates from NOAA's Office of Law Enforcement. Part of the reduction strategy includes a Ship Strike Rule, which mandates the reduction of speed to 10 knots (12mph or 18kph) for ships at least 65 feet (19.8m) long, along the United States Atlantic seaboard. This initiative is there to protect the general marine life population. However, there is a particular concern over the continued existence of the North Atlantic right whale, whose population growth has remained at zero since 1988.
Once plentiful, the right whale experienced rapid depletion during the early 1900s from unrestrained whaling practices. In 1935 protective measures where initiated to stop the exploitation. However, the population has not yet successfully recovered. Each year, the population tally consistently remains at a sobering 444 members. This number concerns marine life conservationists, as right whale females only give birth roughly once every five years, and the calf gestation period exceeds 12 months. A zero population growth indicates the presence of several factors.
- The possibility of illegal whaling practices exists.
- There are significantly more ship strikes than what is reported.
- The use of sonar could have longer lasting impacts on marine mammals than previously supposed.
- The right whale females are either unwilling or unable to reproduce in response to environmental pollutants.
The National Marine Fisheries Service (NMSF) research indicates that a consistently slower speed reduces marine life injury and death, better preserving endangered species. The findings were significant enough to suggest making the Ship Strike Rule a permanent condition, rather than one subject to expiration every four years. The permanence of this action would allow critically endangered marine mammals the opportunity to traverse impending extinction and put them back on the path towards sustainable growth, while making slower speeds the standard, rather than the exception, on the waterways.
