Collisions with ships are a significant threat to the endangered North Atlantic right whale. To reduce this threat, The National Oceanic and Atmospheric Administration's (NOAA) National Marine Fisheries Service (NMFS) and the U.S. Coast Guard (USCG) established the Mandatory Ship Reporting System (MSRS) in July 1999. Under this system, all commercial ships, 300 gross tons or greater, are required to report to a shore-based station when entering either of two areas surrounding designated… 

The right whale mandatory ship reporting system: a retrospective

Observed declines in ship traffic are likely attributable to the 2008–2009 economic recession, the containerized shipping industry making increased use of larger ships that made fewer trips, and diminished oil/gas US imports as previously inaccessible domestic deposits were exploited.

Effectiveness of mandatory vessel speed limits for protecting North Atlantic right whales

The results suggest the rule requiring all vessels to travel 10 knots or less in 10 seasonal management areas (SMAs) has been effective at reducing right whale deaths, and suggests enlarging SMAs to include additional parts of the right whale migratory corridor.

Assessing a Long-Standing Conservation Program: Mariner’s Perspectives on the North Atlantic Right Whale, Eubalaena glacialis, Mandatory Ship Reporting System

Measures established to protect living marine resources, including those for endangered marine species, are only infrequently evaluated. In this paper we report fi ndings of an online survey designed

Bayesian hierarchichal model for evaluating the risk of vessel strikes on North Atlantic right whales in the SE United States

A primary factor threatening the recovery of the North Atlantic right whale is the on- going risk of collision with large ocean-going vessels. Hence, any viable conservation strategy must include

Spatial Pattern Analysis of Cruise Ship–Humpback Whale Interactions in and Near Glacier Bay National Park, Alaska

It is confirmed that ship speed is an effective mitigation measure for protecting whales and should be applied to other areas where ship–whale interactions are common.

Risk of encounters between North Atlantic right whales and recreational vessel traffic in the southeastern United States

Collisions with and disturbance from watercraft represent significant threats to endangered North Atlantic right whales (Eubalaena glacialis). Although several studies have investigated whale

Factors affecting whale detection from large ships in Alaska with implications for whale avoidance

In response to growing concern over lethal shipwhale collisions, a number of efforts have been developed intended to enhance the ability of ships to avoid whales. However, the effec- tiveness of

Response by vessel operators to protection measures for right whales Eubalaena glacialis in the southeast US calving ground

Combining reduced speeds with recommended routes reduces the probability of right whale mortality from ships by 71.9% from the pre-implementation period, support long-term implementation of both vessel-speed reduction and restricted vessel routes for the survival and recovery of the North Atlantic right whale.



Satellite-monitored movements of the northern right whale

This work used satellite-monitored radiotags to identify the late-summer and fall habitat use patterns of right whales in the western North Atlantic and suggests that one whale spent time at the edge of a warm core ring and others spent extended periods in upwellings.


Although collisions with motorized ships are a recognized source of whale mortality, little has been done to compile information on the frequency of their occurrence or contributing factors. We

Declining survival probability threatens the North Atlantic right whale.

Mark-recapture statistics to a catalog of photographically identified individuals were applied to obtain the first statistically rigorous estimates of survival probability for the North Atlantic northern right whale population, finding an upper bound on the expected time to extinction is 191 years.

Seaport Development and Coastal Management Programs: A National Overview

This article reports on one part of the National Coastal Zone Management Effectiveness study. The national study addressed how well state coastal management programs (CMPs) were implementing various

Demography of the endangered North Atlantic right whale

An analysis of extinction time shows that demographic stochasticity has only a small effect, but preventing the deaths of only two female right whales per year would increase the population growth rate to replacement level, suggesting that the population is not doomed to extinction as a result of the Allee effect.

Right whales (Eubalaena glacialis) on jeffreys ledge : A habitat of unrecognized importance?

North Atlantic right whales (Eubalaena glacialis) are known to spend the majority of the year between the Great South Channel southeast of Cape Cod, and the Nova Scotian shelf. We examined sightings

Coastal State Regulation of International Shipping

This book takes a fundamentally different approach to the rights and freedoms set forth in the Law of the Sea Convention. It looks at international shipping from the perspective of those who live in

Climate and the conservation biology of North Atlantic right whales: the right whale at the wrong time?

Demographic projections predict that the North Atlantic right whale population will become extinct in less than 200 years, and extrapolations suggest that reducing mortality rates by a few female deaths per year through conservation efforts would support a slow recovery of the population.
