As a non-profit organization, we often rely on the generosity of our friends and partners to help support our mission. Now, we feel it’s our time to give back, to recognize and support the small businesses that have been dramatically impacted by COVID-19 and that help support Whale Trust throughout the year. 

Sherri Reeve, Maui Artist
Sherri Reeve Gallery and Gifts (Makawao, Hawaii)

To know Sherri Reeve is to know her generosity. Since the doors of her gallery first opened in 1997, she has supported Whale Trust –and countless other Maui based non-profit organizations — including her beloved Hospice Maui, where she currently serves on the board of directors.

For the last 15 years, Sherri has generously supported Whale Trust through direct contributions, donations of her artwork, donor referrals, and placement in her bestselling annual calendar. But nothing stands out as much as her contributions to Whale Tales that started with her volunteering to teach children to craft whale tails as part of our keiki education programs, and her now iconic role in donating the art for our annual Whale Tales t-shirts.

Sherri grew up on Oahu and has called Maui home since 1989. Her collection, inspired by the colors and scenes of Hawaii, spans more than 25 years, and can be found in private art collections around the world — both as gallery art pieces and in her iconic apparel line.

Please join us in supporting Sherri Reeve Gallery and Gifts by shopping online during this time when her doors have to be closed.

WHAT ALASKA’S MELTING FRONTIER TELLS US ABOUT A CHANGING WORLD
Minimum $20 a person suggested donation, all proceeds benefit Whale Trust
Limited tickets, reserve here.

As an artivist, Kristin Hettermann uses photography and storytelling as a way to spread awareness for important issues concerning the ocean. From that intent, she created THE BIG MELT, premiering at Art Project Paia in their recent climate-change fueled show SHE WAS BLUE. A photo collage of fifty-four pieces that spans 9 feet by 6 feet, THE BIG MELT showcases recent glacial photos in a chart that models 900 billion tons of glacier ice loss over fifteen years in Alaska. 

Hettermann spent only one morning, August 30, 2019, photographing the Sawyer and South Sawyer Glaciers in Tracy Arm, Southeast Alaska. She was mesmerized by the crashing sounds, varied textures, and deep striations of blue that this experience shared with her, her first opportunity to observe a glacier up close and personal. As fascinated as she was with the beauty of the scene, she could not help but tune into the chatter of the locals speaking of the unprecedented melting that had been seen over the past two years. 

Upon returning home, she started researching and was shocked by the science she saw coming out of our northernmost border state. “I was dumbfounded to learn that from 2002-2017, Alaska glaciers thinned by an average of several feet per year; 60 billion tons of ice a year equals 900 billon tons of ice over fifteen years,” stated Hettermann. Her inquiries led to the writing of an opinion piece in Scientific American, Iceless in Alaska.

On December 28th Hettermann will open Art Project Paia’s SHE WAS BLUE Event Series with, “WHAT ALASKA’S MELTING FRONTIER TELLS US ABOUT A CHANGING WORLD.” She will be joined by her fiancé, Sven Lindblad, CEO and Founder of global expedition company Lindblad Expeditions. Sven will share insights about the changes he has seen over his nearly 40 years of exploring Alaska and what a changing climate in Alaska might portend for the island of Maui.

“I hope seeing the beauty of the shots while observing the big picture of the loss will elicit a deeper level of understanding in the challenges that our planet is facing,” Hettermann says. “The reality is, what happens in one part of our planet is not geographically limited. Climate change is a global problem. There are things we can do in our everyday life to make a difference, we just need to say yes. 

Saying ‘yes’ to making individual behavior changes requires an understanding of which things have the greatest impact. Hettermann and Lindblad will feature Rare, an organization which inspires change so people and nature thrive. In 2020, Rare is launching an ambitious, multi-year climate change program to empower individuals to take the most meaningful emissions reducing actions. Over the past 40 years, Rare has successfully executed over 450 campaigns in over 60 countries, measurably mitigating threats to fisheries, freshwater, and forests – and the communities that depend on them – in countries hardest hit by climate change.  

A portion of proceeds from the sales during this event will benefit Whale Trust based on Maui, supporting research efforts surrounding how climate change is affecting our humpback whales.

HUMPACS SURVEY RESULTS PUBLISHED

Autonomous (Robotic) Wave Glider Mission from Hawaii to Mexico Detects Humpback Whale Calls in Tropical Mid-Ocean and Questions Definition of Winter Breeding Assemblies

Current NMFS humpback whale management policies assume Mexico and Hawaii winter assemblies are distinct with separate status and management warranted

BIG ISLAND, HAWAII – Jupiter Research Foundation and Whale Trust are pleased to announce the publication of the results of the first leg of their autonomous Wave Glider HUMPACS (Humpback Pacific Survey) acoustic survey in The Journal of the Acoustical Society of America – Express Letters. During a 100-day nearly 7,000 km (3,800 nm) round trip survey on a line between Hawaii and Mexico, during winter breeding season of 2018, humpback whale calls were heard in mid-ocean basin, halfway between the known near-shore assemblies. 

“They’re not ‘supposed’ to be there,” says Dr. Jim Darling, Whale Trust biologist and project partner. Humpbacks are known to assemble in specific near-shore, relatively shallow, breeding grounds in Mexico and Hawaii. “But then no one has looked in these more remote, offshore areas either.”

Mission control was from Puako, Hawaii where Beth Goodwin, Jupiter Research Foundation VP and HUMPACS Project Manager, and her team were in daily communication with the Wave Glider: monitoring status, downloading surface and underwater photographs, downloading short samples of recordings via satellite, and making course alterations if needed.

From January 16 to April 25, 2018, the Wave Glider, named Europa (after one of Jupiter’s moons), performed a 6,965.5 km, 100-day (RT) continual acoustic survey from Hawaii towards Mexico circa 20° N. The survey resulted in 2,272 hours of recordings and included over 4,000 cetacean calls.  Of these calls, 2,048 were identified as humpback whale calls.

The humpback calls were recorded up to 2,184 km (1179 nm) offshore spanning 30 days between January 20, when the Wave Glider left Hawaii, to February 23, 2018. On many days, multiple humpback call detections were recorded (up to 377 calls over 23 hours of a day). Actual numbers of whales cannot be determined, as one whale can make many calls.

“This was risky, we had no idea if humpbacks were even out there,” says Goodwin. “And then, even if they were, there were needle-in-haystack odds of intersecting them considering the size of the Wave Glider and the size of the ocean.”

Possible explanations, suggests Darling, include an undocumented migration route to Hawaii, a separate (from Hawaii and Mexico) offshore assembly of humpback whales, or travel between Mexico and Hawaii assemblies within the same season. At the very least, these results indicate an extension of winter distribution and habitat of humpbacks. It could also be that these offshore whales have not been included in current population estimates.

Since 2016, the model used by the U.S. National Marine Fisheries Service (NMFS) to manage humpback whale populations has treated the Mexico and Hawaii winter assemblies of humpback whales as distinct populations. As such, these populations have different status under the U.S. Endangered Species Act (ESA): Mexico humpback whales are considered threatened while Hawaii humpback whales have been delisted; that is, the Hawaii population has no protection under the ESA.

This assessment is further complicated by longstanding research showing shared song between the breeding assemblies and an interchange of photo-identified individual whales between these two winter breeding grounds.

Our findings question the independence of Mexico and Hawaii humpback whale populations and illustrate the huge potential for the use of autonomous vehicles in the study of whales across remote locations of the ocean.

“We feel certain our results will encourage more research, affect how humpback and other whales are monitored, and help with management,” says Goodwin.

BACKGROUND

Wave Glider

The Wave Glider (produced by Liquid Robotics, a Boeing Company) consists of a surfboard-sized surface platform (the float) tethered by an umbilical cable to a submerged glider (the sub) 8 m (26 ft.) below the surface. The float includes a command and control unit, three solar panels, an instrument package, surface and underwater cameras and communications systems. The sub is the propulsion unit, which transforms vertical wave movement into forward motion (https://www.liquid-robotics.com/wave-glider/how-it-works/). Time-lapse series of images from the two Europa cameras, surface and underwater, are accessible on the JRF blog:

Mixing of Humpback Whale Populations Across the North Pacific

by

FOR IMMEDIATE RELEASE:

Current NMFS humpback whale management policies assume four distinct populations in the North Pacific. Song studies suggest an alternate population model is warranted.

MAUI, HAWAII June 5, 2019 – Whale Trust researchers and international colleagues are pleased to announce the publication of a multi-year study involving song comparison between four locations spanning the North Pacific in Scientific Reports, an online open-access journal from the publishers of Nature. Shared song composition between humpback whales found in Philippines, Japan, Hawaii and Mexico in winter indicates ongoing mixing of ‘populations’ at some point during their annual cycles. Convergence of song over this three-year period recalls similar song transmission when humpback whales off east coast of Australia adopted a song from a western Australia population during a late 1990s’ study.

“Mixing may be the rule, not the exception and part of the biology of North Pacific humpback whales,” says project leader Dr. Jim Darling, who has spent his career studying humpback whale singers and their song.

Studies over at least 35 years (1977-2013) have shown humpback whales in these different winter assemblies have shared all, or portions of these ever-changing complex songs, as cited in a comparison included in this study. The common song across the North Pacific over the long-term indicates ocean-wide interaction and the composition’s fluid nature, annual variable mixing. While acoustic contact is necessary to song transmission, Darling cautions its mechanics, and the purpose of the song for the whales, are not fully understood.

For scientists, the song provides an acoustic identity, since each singer in a ‘population’ sings the same version of the ever-changing song. Singers, exclusively male, broadcast the song starting in fall, continuing through the winter migrations, and tapering off in spring before summer feeding. Recorded by hydrophone by teams of scientists across these four locations, the song’s composition was compared and analyzed by Darling.

“Song composition appears to reflect the recent interactions of populations of whales,” says Darling. Shared song suggests these populations may not be as independent of one another as outlined by management policies in effect. While Hawaiian humpbacks were delisted from endangered status in 2016, a reevaluation of their relationship with populations in Asia and Mexico may be warranted.

“Song should be considered when defining humpback whale populations across the North Pacific,” says Darling.

Currently, NOAA/NMFS (National Marine Fisheries Service) does not include song amongst the data determining populations.

“We may be making decisions around population management based on a model which doesn’t reflect humpback whale behavior in the North Pacific,” posits Darling.

The question must be posed, how can Mexico whales be ‘threatened’ and Asian whales “endangered” but Hawaii whales “warrant no protection” when it’s clear all three groups are integrated?

“We have been delighted to collaborate with Dr. Jo Marie Acebes in the Philippines, Manami Yamaguchi in Ogasawara, Japan, and Dr. Jorge Urbán and Oscar Frey in Baja and mainland Mexico,” says Whale Trust’s Executive Director, Dr. Meagan Jones. “This study would not have been possible without them. Thank you to all who supported this project and continue to support these independent studies across the Pacific.”

BACKGROUND

CURRENT MANAGEMENT

The NOAA/NMFS (National Marine Fisheries Service) review of humpback whale populations that informed the decision to delist Hawaiian humpbacks from the endangered species list in 2016 divided the North Pacific population into four Distinct Population Segments and designations:

Central American – Endangered

Mexico – Threatened

Hawaii – No protection warranted

Western North Pacific – Endangered

For the sake of management, these groups are considered independent of one another. The conclusions were reached after a review of “genetic data, tagging and photographic-ID data, demographic information, geographic barriers, and stranding data.” Notably, songs were not considered in these deliberations. The songs suggest that, in fact, these populations are interactive − and potentially dependent on one another. The two views are so contradictory that implications to management going forward are significant.
