“…There is a high risk of being hit by ships, or tangled in fishing gear. Of the 70 North Atlantic right whale mortalities recorded between 2003 and 2018, 42% were due to ship strikes while 58% were due to entanglement in fishing lines (Sharp et al, 2019). Although many whale strikes go unreported (Jensen et al, 2004), numbers are known to be high for numerous whale species throughout the world (Monnahan et al, 2015;Di-Méglio et al, 2018).…”

Climate change is expected to dramatically alter the distribution of many marine megafauna, impacting the people and economies that depend upon them. We build on the recent literature by developing a framework to describe the effects these changes will have on marine megafauna. With the goal to assist policymakers and grass roots organizers, we identify three illustrative pathways by which climate change drives these range shifts: (1) effects on habitat and shelter, (2) impacts on reproduction and disease, and (3) changing distribution of sources of food. We examine non-climate factors that may constrain or enable megafauna to adapt, creating winners and losers both for the species and the people dependent upon them. Finally, we comment on what management strategies exist at international and local scales that could help mitigate these impacts of climate change so that we, as a global community, can ensure that marine megafauna and people can best co-exist in a changing world.

“…Campbell‐Malone et al (2008) report that the mandibles of North Atlantic right whales ( Eubalaena glacialis ; hereafter, right whales) were fractured in one‐third of the necropsies they examined where blunt trauma was identified as cause of death. Sharp et al (2019) reported that 8 of 10 right whales killed by blunt trauma had fractured bones. Similarly, three of the four right whales determined to have died as a result of blunt trauma in Canada in 2017 had acute internal hemorrhages, but, importantly, just one of these animals had bone fractures that were attributable to the blunt trauma that resulted in the death of the animal (Daoust, Couture, Wimmer, & Bourque, 2018).…”

Assessing the lethality of ship strikes on whales using simple biophysical models

Studies of ship strikes on whales often focus on large vessels (>20 m), with attention to their speeds and the resulting risk of lethality. Smaller coastal vessels also co-occur with whales, resulting in collisions that merit study. To cast light on injuries caused by vessels of all sizes, we used knowledge of right whale anatomy and Newtonian mechanics to construct simple models that predict the mechanical stresses experienced by whales during collisions. By comparing our predictions with published models and with data from ship strikes on various whale species, we developed a model for lethal injury as a function of several vessel and whale properties, finding that collisions that create stresses in excess of 0.241 MPa were likely to cause lethal injuries to large whales. Furthermore, this model has revealed that (1) vessels of all sizes can yield stresses higher than this critical level, and (2) large vessels produce stresses much larger than this even when travelling at reduced speeds (i.e., 10 knots). The model is fast enough to power an interactive GUI-based tool (in R) and flexible enough to simulate strikes by vessels of different masses and speeds upon whales of different species, sizes, and physical conditions.

“…Although collisions with vessels are a leading cause of mortality for the North Atlantic right whale (Sharp et al 2019), other shortand long-term effects of vessel activities on North Atlantic right whales are less understood, especially for smaller, recreational vessels and within the calving ground of these whales. However, previous studies have shown that vessel-related activities could displace whales (Salden 1988, Smultea 1994, Rowntree et al 2001 and modify their short-term behavior (e.g., decreasing resting and socializing time and increasing traveling time) (Vermueulen et al 2012, Lundquist et al 2013.…”
