Members of Pacific Whale Foundation’s Research team recently attended the 24th Biennial Conference on the Biology of Marine Mammals in Florida. This important conference brought together scientists, policymakers, managers and advocates for five days of presentations, workshops and constructive dialogue. Four team members attended the conference with support from PWF Member Grant Crosby who donated his Alaska Air miles to cover the airfare.
“This conference is one of the largest gatherings worldwide for researchers to come together to discuss the latest in science and conservation for marine mammals,” noted attending PWF Research Biologist Grace Olson.
In an effort to be more inclusive to all attendees, this was the first fully hybrid, live-virtual conference of the Society of Marine Mammalogy. The energy at the in-person event was considerably elevated as most attendees were experiencing actual contact with other scientists and researchers for the first time in a few years.
“I was very excited to finally attend — especially after the conference had been delayed from 2021 due to the ongoing COVID-19 pandemic,” Olson continued. “During the week-long conference, I delivered a presentation on our study that assessed the spatial overlap of vessel traffic and two species of dolphins in Maui Nui, Hawai‘i.” It was particularly exciting to engage with those who sought out her work, she added.
Another attendee, PWF Research Analyst Florence Sullivan, said she found it particularly inspiring to “exist in a space where scientists collaborate with managers to create informed, dynamic, practical solutions to difficult problems.”
As a presenter of PWF’s Whale and Dolphin Tracker mobile phone app, Sullivan made sure to attend other presentations focused on community science and app-based data collection. “I made connections with researchers working in Norway, Cameroon and the Caribbean, and came away with some ideas to incorporate into our app, so now it’s time to get to work” she added. “In the ‘strategies for science communication’ panel, someone shared that ‘people act when they have hope’ and the best way to create change is to ‘reconnect with your hope, and then share that hope, because it multiplies.’”
24th BIENNIAL CONFERENCE ON THE

According to PWF Research Biologist Abigail Machernis, the 2022 SMM conference was full of optimism and inspiration. “Many of the in-person conference attendees expressed how exciting it was to reconvene in person again to share our work,” she revealed.
Machernis, who is responsible for curating PWF’s Hawai’i humpback whale catalog, which is vital to ongoing threat mitigation efforts facing these whales, said she was also drawn to one of the larger topics presented at the conference: the blight of the critically endangered North Atlantic right whale (NARW) at risk from continued entanglement in fishing gear and vessel strikes. “Although PWF research does not directly focus on this species, the whales and dolphins in our region face similar threats,” she explained. “As such, many of the research techniques and lessons learned from the NARW can be applied directly to our work.”
Olson agreed, adding that many of the presentations were focused on human-based threats facing marine mammal populations worldwide. “To help with conservation and protect species from these threats, many aspects of the conference focused on science communication,” she elaborated. “It was reinforced that, as scientists, we need to get research out to the general public to raise awareness and encourage change. I hope to be able to connect with the public and share our work at PWF in a way that can inspire others.”
Virtually attending the conference, PWF Research Assistant Elizabeth Beato commented on the incredible opportunity it provided in gaining insight into how scientists around the world are approaching similar threats to marine mammals in various ways. “Attending presentations, speed talks and poster sessions focusing on the same species that PWF studies, both the same populations here in Hawai‘i as well as other populations around the world, sparks new ideas to apply to our current research projects. It allows us the opportunity to investigate various methods and approaches to answering questions about threats to our local populations of whales and dolphins in Maui Nui,” she explained. “I am grateful for the opportunity to gain a better understanding of research that is currently in the works around the world. Listening to the various obstacles and solutions other scientists have encountered, allows PWF to learn from these and solve potential obstacles within our own datasets and studies.”
Regarding the conference’s success in illuminating new study results and measures to help mitigate several ongoing threats to cetaceans worldwide, Sullivan concurred with the overarching takeaway PWF attendees experienced, “My hope from this conference is that we are not alone in our care for our ocean,” she concluded. “There are so many excellent people working in so many places along the spectrum, from understanding biological functioning to ecosystem level cascades to the creation of global policy. Together, if we move forward and choose to act, we can make a difference.”
