New publication on Co-occurrence of gray whales and vessel traffic (Gregory Silber)
by Greg Silber 02 Mar '21

02 Mar '21

Colleagues: My co-authors and I are pleased to share our recent publication: Co-occurrence of gray whales and vessel traffic in the North Pacific Ocean. The paper is open access and is available at: https://www.int-res.com/abstracts/esr/v44/p177-201/ Silber GK, Weller DW, Reeves RR, Adams JD, Moore TJ. 2021. Co-occurrence of gray whales and vessel traffic in the North Pacific Ocean. Endang Species Res 44:177-201. https://doi.org/10.3354/esr01093 and https://www.researchgate.net/publication/347168620_Co-occurrence_of_gray_wh… ABSTRACT: All species of large whales are susceptible to vessel strikes, but the true scale and geographical extent of such strikes is not known. This paper provides a qualitative assessment of the range-wide risks posed to gray whales Eschrichtius robustus by vessels, by comparing patterns of whale distribution with the density of vessel traffic seasonally throughout the North Pacific in 2019. Areas of very high vessel density were evident year-round near many coastlines, along inter-continental trade routes, and at hubs of commercial shipping near port entrances. Gray whales were exposed to vessel strikes throughout their range and in their feeding, southbound migration, wintering, and northbound migration periods. Areas of apparently high risk were in the Russian Far East (Kamchatka peninsula and Okhotsk Sea), Bering Sea (including the Aleutian Islands), Gulf of Alaska, and along the entire west coast of North America. Risk appeared greatest during south- and northbound migration when much of the gray whale population is moving through waters near shore. Tanker, container, and bulk-carrier ships represent considerable risk to whales in the North Pacific Ocean, but the large geographical extent of commercial fishing activities suggests that fisheries are also a substantial source of risk. Vessel-strike risk maps indicate the relative extent of exposure of gray (and other) whales to underwater vessel noise. The number of gray whales killed by ship strikes each year may be in the tens, or perhaps the low hundreds. Additional analyses, including quantitative assessments, are warranted to further clarify the risk of vessel strikes to gray whales. Gregory Silber gregsilber2(a)gmail.com

New publication on a diel patterns in singing activity of humpback whale in Okinawan waters
by 小林　希実 01 Mar '21

01 Mar '21

Dear MARMAM community, My co-authors and I are pleased to announce you on our new publication titled, Diel patterns in singing activity of humpback whales in a winter breeding area in Okinawa (Ryukyuan) waters, which is now available in the journal of Marine Mammal Science. by Nozomi Kobayashi, Haruna Okabe, Naoto Higashi, Hirokazu Miyahara, Senzo Uchida Abstract Male humpback whales produce complex sounds known as songs during their breeding season. Previous studies have shown diel patterns of song in their breeding areas, but there had been no similar studies in the breeding area around Okinawa, Japan. To study diel patterns of song and the behavior of humpback whales in Okinawa, we conducted 24 hr recording with a fixed hydrophone in 2007, and vessel‐based sighting surveys during 2014–2017. Song was monitored for 15days, with peaks at sunrise and around 2200. Singing activity declined significantly between sunrise and sunset, then increased until 2200. Activity levels at night were higher and more stable than during the day. During 278 days of sighting surveys, 2,551 whales in 1,382 groups were observed. 79 individuals were confirmed as singers, all of which were lone whales. In six cases, singing individuals stopped singing before joining a group or began singing after leaving a group. Previous studies have shown that group size of humpback whales increases through the day. Considering the results from our study and the former studies, the decrease in singing activity as the day progresses may be a result of aggregation increasing, thus reducing the number of lone singers during the day. This article can be obtained from https://doi.org/10.1111/mms.12790 Please feel free to contact us if you have any questions!

New publication: Marine algal toxins in California cetaceans
by Kerri Danil - NOAA Federal 01 Mar '21

01 Mar '21

We are pleased to announce our new publication: Danil, K., Berman, M., Frame, E., Preti, A., Fire, S.E., Leighfield, T., Carretta, J., Carter, M.L., Lefebvre, K., 2021. Marine algal toxins and their vectors in southern California cetaceans. Harmful Algae 103, 102000. https://www.sciencedirect.com/science/article/pii/S1568988321000275?dgcid=a… ! Abstract: Published baseline data on biotoxin exposure in cetaceans is sparse but critical for interpreting mortality events as harmful algal blooms increase in frequency and duration. We present the first synthesis of domoic acid (DA), saxitoxin (STX), okadaic acid (OA), and microcystin detections in the feces and urine of stranded and bycaught southern California cetaceans, over an 18 year period (2001–2018), along with corresponding stomach content data. DA was detected in 13 out of 19 cetacean species, most often in harbor porpoise (*Phocoena phocoena*) (81.8%, *n* = 22) and long-beaked common dolphins (*Delphinus delphis bairdii*) (74%, *n* = 231). Maximum DA concentrations of 324,000 ng/g in feces and 271, 967 ng/ml in urine were observed in *D. d. bairdii*. DA was detected more frequently and at higher concentrations in male vs. female *D. d. bairdii*. Higher fecal DA concentrations in *D. d. bairdii* were associated with a greater proportion of northern anchovy (*Engraulis mordax*) in the diet, indicating it may be a primary vector of DA. Fecal DA concentrations for *D. d. bairdii* off Point Conception were greater than those from animals sampled off Los Angeles and San Diego counties, reflecting greater primary productivity and higher *Pseudo-nitzschia* spp. abundance in that region and a greater abundance of *E. mordax* in the diet. STX was detected at low levels (fecal max = 7.5 ng/g, urine max = 17 ng/ml) in 3.6% (*n* = 165) of individuals from 3 out of 11 species. The occurrence of *E. mordax* in 100% of the 3 examined stomachs suggests this species could be a primary vector of the detected STX. OA was detected in 2.4% of tested individuals (*n* = 85) at a maximum fecal concentration of 422.8 ng/g. Microcystin was detected in 14.3% (*n* = 7) of tested individuals with a maximum liver concentration of 96.8 ppb. -- Kerri Danil (she/her) Research Biologist, Southwest Fisheries Science Center NOAA Fisheries | U.S. Department of Commerce Office: (858) 546-7001 Stranding hotline: (858) 546-7162 https://www.fisheries.noaa.gov/west-coast/science-data/cetacean-health-life… https://swfsc-publications.fisheries.noaa.gov/publications/?search=danil

Survey on photo-ID data management
by PhotoID Survey 01 Mar '21

01 Mar '21

Greetings, We are reaching out to the greater marine mammal research community to better understand photo-ID data archival challenges and how you all manage these challenges. Some challenges include the availability of and access to well-supported archival platforms that provide multi-decadal stability, access to image processing and analysis tools, and cross-collaborative data-sharing functions. Other concerns may be related to public accessibility, proper attribution for catalog curators and funding sources, and the registering of persistent identifiers (e.g., DOIs) for archives. We encourage all marine mammal researchers who manage photo-ID data collections to respond to the survey link below. The survey will only take a few minutes to complete and it is anonymous. The results will be used to inform a presentation submitted to the Society for Marine Mammalogy Biennial Conference in December 2021. Please feel free to forward the survey link to other marine mammal researchers. If applicable, kindly coordinate with your team to avoid duplicative responses. The survey will be available for responses until Sunday, March 14, 2021. Link: https://forms.gle/ND8MKvCkWKGpcS3b7 We appreciate your help and interest.

Webinar - March 11, 2021, 12:30-1:30 EST - Persistent Contaminants and Herpesvirus Infection are Positively Correlated with Cancer in Wild Sea Lions
by Sarah Wilkin - NOAA Federal 01 Mar '21

01 Mar '21

*We invite everyone to join us for a webinar on Cancer in Wild California Sea Lions on March 11, 2021 from 12:30-1:30pm EST hosted by the NOAA Library.* *Register for the webinar is here:* https://register.gotowebinar.com/register/5102268728787699984 Speakers: Dr. Frances Gulland, University of California, Davis; Dr. Alissa Deming, Pacific Marine Mammal Center, California; Prof. Ailsa Hall, University of St Andrews, Scotland; Dr. Irvin Schultz, Northwest Fisheries Science Center, Seattle, WA Abstract: The prevalence of cancer in wild California sea lions (Zalophus californianus) is one of the highest in mammals, with 18–23% of adult animals examined post-mortem over the past 40 years having urogenital carcinoma. Multiple factors have been identified in association with this carcinoma: sea lion genetics, infections and organochlorine pollutants. Two recent publications this year (Gulland <https://www.frontiersin.org/articles/10.3389/fmars.2020.602565/full> et al. and Deming <https://www.mdpi.com/2076-2615/11/2/491> et al.) demonstrate that genital herpesvirus infection plays an integral role in carcinogenesis and the importance of persistent organochlorines combined with OtHV1 infection in cancer occurrence in wild sea lions. These sea lion studies provide evidence that herpesvirus infection (OtHV1) is critical to the likelihood of carcinoma occurrence, however the higher the animals’ blubber contaminant concentrations, the higher the odds of cancer. * The webinar will also be recorded and available for later viewing on the NOAA Library YouTube site. * -- *Sarah Wilkin, M.S.
