Give the Ocean a Voice

Ai-powered research on Hawaiian Spinner Dolphins

“By listening to marine mammals and understanding their world, we can give a voice to the Ocean and understand the changes it is experiencing. Safeguarding the splendor and biodiversity of this Planet requires us to be in tune with the Tribe of the Sea.”

Our lives depend on the sea; the future of the sea depends on us.

We live on a planet covered by 70% water. Since ancient times native Hawaiians have considered dolphins the tribe of the sea for their cognitive abilities and the way they hunted collaboratively with their tribes of the earth.

Project Overview

Dolium japonicum

We are conducting a long-term cognitive behavioral study using cutting-edge AI technology to obtain critical information on the ecology of Spinner Dolphins living off the coast of Lānaʻi.

Spotted eagle ray

Leveraging new technology, we will gain a comprehensive view of Hawaiian Spinner Dolphins’ social structure and bioacoustic repertoire to understand the modes of intra/interspecies communication.

Communication is the glue union that holds animal societies together. By filming and recording their individual voices in their home bay we will relate their behaviors with their vocalizations and better understand dolphins’ communication and their social associations. Understanding the mechanisms of their communication will enable us to better protect the habitats in which they live.

Why Spinner Dolphins

Cetaceans such as dolphins, are vital for maintaining the ecological balance of marine ecosystems due to their movements and position in the food chain. Together with other large pelagics like sharks, tuna, and sea turtles, they help regulate the populations of the fauna they feed on. Maui Nui spinner dolphins, part of the Oʻahu/4-islands stock, are genetically distinct from other Hawaiian islands and display unique patterns of habitat usage due to the shallow bathymetry of the coastal region.

Hawaiian Spinner Dolphins in the Maui region have historically not been as well studied or understood as other keystone species, yet they are just as critical to the ecosystem.

As tourism grows in Maui Nui, the dolphins of Lānaʻi are under increased pressure from human activities, including dolphin watching. Moreover, the pollution from the tragic fires of Lahaina may have an ongoing impact on the Maui Nui dolphin population. We need to better understand how this population interacts with their habitat, what their needs are, and how humans are impacting their world.

Project Objectives

  • Generate and develop a database of Spinner Dolphins identified through AI-assisted facial recognition technology and individual acoustic repertoire. This will enable us to determine and monitor the residency and loyalty to specific sites of Lānaʻi Island, characterize the group dynamics between individuals, and identify the presence of specific specimens within particular social groups.

  • Analyze and catalog the bioacoustics repertoire of Hawaiian Spinner Dolphins. We will Investigate distinctive signature whistle (SW) development and use it to help expand individuals’ identification to determine whether the population exhibits a specific signature whistle distinctive to the population. Furthermore, we will document the process of interspecies interaction.

  • Leverage AI to examine and relate individual animals’ vocalizations and behaviors to study the Spinner Dolphin social structure: sexing, behavioral sampling, and group dynamics.

Outcome

The knowledge and information we gain will be used to…

  1. Protect and preserve Hawaiʻi’s unique habitats and marine life; 
  2. Monitor animal welfare and ecosystem health; 
  3. Create and put into practice effective management practices to protect the environment and conserve resources; 
  4. Improve conservation education to strengthen the public’s awareness of the importance of the oceans and mālama (take care) of its well-being;
  5. Produce educational materials, marine labs for kids, and outreach activities to reduce Spinner Dolphin disturbance and promote ocean conservation.

A Management Plan

The conclusions from this research will be used to inform the local management plan to protect and conserve the islands’ unique environment and natural resources. The recommendations will prioritize identifying the time periods when dolphins are most susceptible to disturbance, as well as assessing the impact of ecotourism activities to the environment.

AI for Conservation:

Leveraging advanced facial recognition and whistle identification to accelerate and enhance our understanding.

The Challenge:

Traditional marine mammal research and conservation initiatives rely on time consuming identification of photos and bioacoustics. This involves data collection on individual dolphins and partially manual identification of the dolphins from their natural markings and their vocalizations.

The Solution:

AI technology will enable us to expedite the identification of individual dolphins with much greater accuracy.

It will also enable us to estimate age, population size, range, residency, and loyalty to specific sites, and analyze frequencies and features that humans can’t detect—all with a high degree of accuracy, and reliability.

More about Spinner Dolphins

Nai’a – The Hawaiian Spinner Dolphin (Stenella longirostris)

Spinner dolphin
Domain: Eukaryota
Kingdom: Animalia
Phylum: Chordata
Class: Mammalia
Order: Artiodactyla
Infraorder: Cetacea
Family: Delphinidae
Genus: Stenella
Species:
S. longirostris
Subspecies:
S. l. orientalis
S. l. centroamericana
S. l. longirostris
S. l. roseiventris

The Spinner Dolphin is one of the most frequently seen species of cetaceans in the waters off the Hawaiʻi Islands. 

Stenella longirostris are known for their spectacular aerial acrobatics, spinning around their axis up to seven times before landing back into the water. Experts posit that Spinner Dolphins use these behaviors primarily for communication, but they may also serve to remove ectoparasites such as remoras. 

Hawaiian Spinner Dolphins, part of Gray’s subspecies, exhibit a distinct three-banded coloring: dark gray on their back, lighter gray on their flanks, and a pale belly. 

Hawaiian Spinner Dolphins are genetically unique and display different habitat utilization patterns across different islands. Hawaiʻi’s population has five genetically distinct island-associated stocks. These stocks are reproductively isolated, meaning breeding between them is minimal or non-existent.

During the day they seek out calm, shallow, clear bays to socialize, rest, and care for their young. They prefer areas with sandy bottoms, as this gives them the best view of incoming predators. They move to deeper waters at night to hunt, taking advantage of the nightly vertical and horizontal migration that brings their prey species to shallower depths and closer to shore.

Signature whistle (SW)

Signature whistle (SW) is a distinctive acoustic signal. It’s a unique frequency-modulated vocalizations that remain stable throughout dolphins’ life (crystalized) and are developed during animals’ first months.

Study Area

Our study area will focus on the coastal waters of the Hawaiian island of Lānaʻi and the ‘Au‘au channel, with particular attention to the island’s southern coasts, where groups of dolphins typically spend most of their day.

Lānaʻi Island
Lānaʻi, also known as Pineapple Island, is the sixth largest among the Hawaiian islands. It is located approximately 15 km west of Maui and 13 km south of  Molokaʻi , with the Kalohi channel separating it from Molokaʻi and the ‘Au‘au channel from Maui.

Lanai island

Hulopoʻe & Manele bay

Nestled on the southern coast of Lānaʻi Island are two beautiful bays – Manele and Hulopo‘e. These bays are separated by a volcanic cone that has eroded on the seaward edge, creating a beautiful cove that is known as Pu‘u Pehe Cove. In the middle of the bay, there is a sandy channel that provides a serene and peaceful resting spot for dolphins.

West Maui Coastal Sites

 

 

In addition to Lānaʻi Island and the ʻAuʻau Channel, the study area includes selected coastal sites along West Maui known for consistent spinner dolphin presence.
These sites include Honolua Bay and Kahekili Beach Park, both of which provide important nearshore habitat used by dolphins for daytime resting and socializing.

Honolua Bay is characterized by sheltered reef systems and calm nearshore waters, while Kahekili Beach Park features a gently sloping coastline with sandy substrates and patchy reef. Together, these sites complement the Lānaʻi study areas by capturing dolphin habitat use across multiple islands within the ʻAuʻau Channel region.

Our Methods

    • Observe and record animal behavior in their natural habitats, both above and below water surfaces, approaching them in a species-specific way.
    • Exercising caution, we allow the dolphins to decide whether or not to engage with us—adhering strictly to the principles of dolphin etiquette, ensuring that we do not disrupt their daily routine.
    • Capture underwater videos and high-frequency acoustic recordings with technology able to recognize the directionality of the vocalizations emitted by the animal on the recorded video.
