One Ocean Diving Research

Founded as a research program, One Ocean Diving has a number of different research studies currently in progress! Take a look below at some of the research One Ocean Diving is involved in!

Our ongoing correlation studies look at shark movements by species, gender, depth profile, and season. Baseline information for individual animals is recorded, and new sharks are added to our ID program. The Shark ID program significantly reduces the need for tagging to determine site fidelity and assists in accuracy of survey counts. Deep water camera systems (up to 500 feet) are deployed to study shark movements at every depth at survey sites. 

Other correlation studies in the collaborative data set look at weather and how environmental conditions impacts or influences behavior and lack or abundance of apex vs. meso-predators in deep water reef ecosystems.

Recently we have expanded our shark research to include human interaction and impact, environmental impact, metal and magnetic testing, and social dynamics in schooling sharks.

We use our data to support a platform for research that is used to benefit BOTH human communities and shark and marine life populations!

We have just recently introduced our Honu Program and are excited to begin our studies on the effects human impacts have on the success and health of the green sea turtle. Just like the shark program we have a Honu ID program that relies on a photo database in order to get a baseline of the population. We utilize photos instead of tagging to reduce the amount of stress placed upon the animal. We take photos of the left, right and top profile of the turtle's head and note any distinct markings and the shape and placement of the facial scales. 

Our main focus is on entanglement issues and the Fibropapillomatosis virus that is highly common among Green sea turtles. When we come upon an entangled sea turtle we take note of the type of gear, location, types of injuries, appearance or state of the sea turtle, photo ID and efforts to remove the gear off the sea turtle. Our goal is to better understand what types of gear more highly affect sea turtle health.

Fibropapillomatosis is a virus that is specific to sea turtles and it involves the growth of tumors, usually on the eyes, nose and mouth area. However, they have been found to cover almost any part of the body. We are studying the pattern of the virus among sea turtles along Oahu's coast.

Our hope is to use the data we have collected to better protect our endangered Hawaiian Green Sea Turtle, and to better understand its use of the beaches and shallow water's off the coast of Oahu.




Our current Humpback whale research looks at tail fluke ID for all individuals. We also record the sex (male or female), age (adult or calf), and pod/pair relationships. The data we collect we will share with other whale research groups to add to their data set.
