Our research in Hawaii occurs in the four-island region of Maui, which includes the waters surrounding the islands of Maui, Kahoʻolawe, Lanaʻi and Molokaʻi. We study humpback whales and numerous species of odontocetes using both systematic and opportunistic data collection methods. Some of our current studies are described below.
Whale & Dolphin Tracker
Whale & Dolphin Tracker is an application created by Pacific Whale Foundation to collect scientific data about marine wildlife in the four-island region of Maui, Kahoʻolawe, Lanaʻi and Molokaʻi. Marine wildlife sightings are recorded by researchers onboard our dedicated research vessel Ocean Protector, and by our certified Marine Naturalists onboard PacWhale Eco-Adventures. The GPS location, group dynamics, observed behaviors, and other data is logged in real time and uploaded instantly to our research database.
Members of the public can use Whale & Dolphin Tracker and participate in our research as citizen scientists by submitting marine wildlife sightings from any location around the world. Whale & Dolphin Tracker allows you to log sightings in real time, create a full GPS track, and upload photos from your mobile device. Your contributions will add to a global database that will help researchers track and monitor cetaceans, determine patterns of species distribution, and study marine animal interactions with their environment.

North Pacific Humpback Whale Catalog
The humpback whale photo-identification (or photo-ID) project involves photographing and cataloging flukes, which are the underside of a humpback whale’s tail. Each whale has unique features, including the overall shape of the flukes, the shape of the trailing edge, any acquired scars, and natural pigmentation patterns. The flukes thus help identify individual whales when captured in digital photos.
In addition, we record GPS data, behavioral displays, pod composition, and other observations at the time each fluke photo is taken. This information is centrally filed and used to identify and track individual whales over time. Database software is used to catalog individual whales and match them to new sightings. Photo-ID catalogs serve as a non-invasive way to gather information on the life histories of individual animals, including minimum age, site fidelity, sighting rate, and migratory movements.
Although North Pacific humpback whales are an iconic species in Maui waters, there is still a lot to learn about their life history, behavior, and migration patterns. Through this catalog, we aim to advance our understanding of humpback whale biology and population status to help further conservation and management efforts. For this project, we are using photo-ID data from multiple sources, “platforms of opportunity” such as whalewatch ecotours, as well as photo donations from the public.
Odontocete distribution, abundance, and life-histories
Odontocetes are toothed whales and dolphins, and relatively little is known about most odontocete species found in the waters surrounding Maui. We aim to monitor trends in their distribution, abundance and movement patterns throughout the four-island region of Maui. To do this, we are conducting line transect surveys and collecting data using distance sampling methodologies.
Social structure of false killer whales in Maui
There are two populations of false killer whales in Hawaiian waters: an offshore population and an insular (island-associated) population. Both populations have experienced a decline due to multiple threats including fisheries interactions, ingestion of marine debris, and exposure to anthropogenic noise pollution. Due in large part to these threats, the insular population has recently been listed under the Endangered Species Act. This research project is focused on using photo-identification to increase our understanding of the social ecology and behavior of false killer whales in Maui waters in order to better conserve and manage the species.
Land-based study of effects of vessel presence on whale behavior
Our research conducted during the Surprise Encounters with Humpback Whales study (2013 – 2016) collected data from vessels to understand the risk of vessel collisions of whales. To complement our vessel-based surveys, land-based observations of humpback whales will allow us to assess how the presence of a vessel may affect the whales’ behavior.
