“…While progress has been made in projecting large-scale prey resource changes (e.g., Stock et al, 2014;Lefort et al, 2015), marine mammal species such as blue whales (Balaenoptera musculus) show tight coupling to smaller scale oceanographic features (Fiedler et al, 1998;Moore et al, 2002;Croll et al, 2005) associated with high euphausiid (krill) abundance (Santora et al, 2011). Similar relations have been exhibited by bowhead whales (Balaena mysticetus) across the Arctic (Laidre et al, 2007;Citta et al, 2015;George et al, 2015) and North Atlantic right whales (Baumgartner et al, 2003;Baumgartner and Mate, 2005).…”

Projecting Marine Mammal Distribution in a Changing Climate

Climate-related shifts in marine mammal range and distribution have been observed in some populations; however, the nature and magnitude of future responses are uncertain in novel environments projected under climate change. This poses a challenge for agencies charged with management and conservation of these species. Specialized diets, restricted ranges, or reliance on specific substrates or sites (e.g., for pupping) make many marine mammal populations particularly vulnerable to climate change. High-latitude, predominantly ice-obligate, species have experienced some of the largest changes in habitat and distribution and these are expected to continue. Efforts to predict and project marine mammal distributions to date have emphasized data-driven statistical habitat models. These have proven successful for short time-scale (e.g., seasonal) management activities, but confidence that such relationships will hold for multi-decade projections and novel environments is limited. Recent advances in mechanistic modeling of marine mammals (i.e., models that rely on robust physiological and ecological principles expected to hold under climate change) may address this limitation. The success of such approaches rests on continued advances in marine mammal ecology, behavior, and physiology together with improved regional climate projections. The broad scope of this challenge suggests initial priorities be placed on vulnerable species or populations (those already experiencing declines or projected to undergo ecological shifts resulting from climate Silber et al.Projecting Marine Mammal Distributions changes that are consistent across climate projections) and species or populations for which ample data already exist (with the hope that these may inform climate change sensitivities in less well observed species or populations elsewhere). The sustained monitoring networks, novel observations, and modeling advances required to more confidently project marine mammal distributions in a changing climate will ultimately benefit management decisions across time-scales, further promoting the resilience of marine mammal populations.

“…Other variants for the North Pacific blue whale song type have been reported by . The range for the North Pacific blue whale song type (Type 4 in Figure 31) is primarily from the Aleutian Islands, stretching to about 40 ?N (Moore et al, 2002). Lesser numbers of calls are heard as far south as Hawaii and Wake Island ).…”

“…Previous studies have used the characteristics of vocalizations to determine the seasonal presence and movement of blue whales through a region (e.g. Clark, 1995;Moore et al, 2002) including the possibility of populations mixing within a region ) and have used differences in blue whale song to identify populations and to distinguish populations from neighbouring ones (e.g. Northeastern vs Northwestern Pacific Moore et al, 2002) and Antarctic versus others (Stafford et al, in press).…”

Acoustic recordings and shipboard surveys were employed to study marine mammal behavior and populations. The ultimate goal of these studies is to determine the potential impacts on the marine mammals from Naval activities. SUBJECT TERMSSouthern California Off-Shore Range (SCORE), marine mammals, acoustics, environmental assessment, SERDP, Orincon Corporation, Art Teranishi principal investigator, collaborated on the collection of sonobuoy array data for the development of array processing tools for fleet applicationThe Naval Post-Graduate School collaborated in data collection within the SCORE range, and usage of range facilities. Principal investigator for this work was Curt Collins, along with coprincipal investigator Chin-Sang Shiu, and Chris Miller.Assistance with algorithm development was provided by Dave Mellinger at the Oregon State University. Assistance with experimental planning, at-sea data collection, and post-processing was provided by Mark McDonald of Whale Acoustic LLP.We thank the US Navy CNO N45, Frank Stone, Ernie Young and Linda Petitpas, and the Office of Naval Research, Bob Gisiner, Jeff Simmons and Ellen Livingston, for support of this work, as well as Robert Holst and the staff at SERDP.
