Rising Tide of Citizen Scientists is Needed in Hawaiʻi

Scientists studying sea level rise at the University of Hawaiʻi at Mānoa need your help. Impacts of some of our highest tides of the year are predicted to be seen this week. And the general public is being summoned to document those impacts along the thousand or more miles of coastline across the island chain. HPR reporter Kuʻuwehi Hiraishi explains how anyone with a smartphone and coastline access can contribute to science.


Who among us hasn’t dreamt of making that big scientific contribution or discovery? If that’s you, the Hawaiʻi and Pacific Islands King Tides Project may be your chance.

GONSER: We’re trying to document these high water level events to give us a snapshot into what could become an everyday occurrence with future sea level rise.

Matt Gonser is with the University of Hawaiʻi’s Sea Grant College Program, and he’s working on recruiting citizen scientists, ordinary folks like you and me, to collect data by snapping photos of what happens when the highest of high tides or King Tides meets sea level rise. Is there flooding? Is there erosion?

MERRIFIELD: What does it actually look like on the ground?

Oceanography Professor Mark Merrifield is the Director of the Center for Coastal and Climate Science and Resilience at the University of Hawaiʻi at Mānoa.

MERRIFIELD: How is the beach affected? Is it running up to the road?

Merrifield has studied sea level rise for over 30 years, and says nothing can quite replace first-hand human observation.

MERRIFIELD: We have a very comprehensive system but it’s not everywhere. It would be great to see what the impacts are like across the state, and that’s where the citizen scientists can really help us.

Last year, Gonser recruited 60 citizen scientists contributing over 500 photosduring two King Tide events. But continuous data collection is needed when it comes to observing the combined impact of natural or cyclical changes like King Tides and sea level rise, which Merrifield says is subtle.

MERRIFIELD: We’re talking about inches of change over decades. It’s not something that you would point out and say that’s sea level rise, and that’s global warming. It’s a little more complicated than that.

According to Merrifield the rate of sea level rise that we’ve been seeing for the last century is going to double and even triple over the next few decades.

MERRIFIELD: And that’s when the awareness of it will be much more abrupt and obvious.

GONSER: The reality is that change is coming and that needs to be a part of the discussion. And that’s what we hope the citizen scientist project can initiate because when you’re out there and you’re experiencing it, you can’t ignore it, it’s real. The inevitability of sea level rise is here and now the discussion moving forward is what can we do about it?

The first King Tides of summer are rising with the new moon tomorrow with impacts to be seen as early as today and lasting through Friday. Project photos and links on how you can get started are available on our website.

Citizen Scientists being Trained for Reef Monitoring in the US Virgin Islands

Crucians Trained to Monitor Reefs

About a dozen St. Croix residents learned Monday evening how to identify coral bleaching and other reef disturbances and how to scientifically report them for monitoring purposes.

Lisa Terry, science technician and dive safety officer for The Nature Conservancy, made the training presentation on what residents need to know to become what she called “citizen scientists.”

BleachWatch is sponsored by The Nature Conservancy and falls under the umbrella of its Reef Connect program. The Reef Connect website was revamped in March and includes everything about BleachWatch, including Terry’s training presentation.

She said she was pleased with the way Monday’s event went. “They asked very good questions and were excited. She added that everyone present took the underwater survey forms that the “citizen scientists” will need to fill out to be part of the program, she said.

For St. Croix residents who missed Monday’s training event, another will be held at 5:30 p.m. Tuesday at The Nature Conservancy in Little Princess. Residents of St. John and St. Thomas will get a presentation on BleachWatch Virgin Islands during the first part of the second week of September. Terry said September and October are the months when bleaching is most likely to occur.

In June the National Oceanic and Atmospheric Administration said a third consecutive year of higher-than-normal sea temperatures could lead to an increase in coral bleaching around the world and in the Virgin Islands.

According to Terry, high school interns performed surveys around St. Croix during July and reported no bleaching, but did find instances of coral disease. However, she indicated that a couple of reports of bleaching on deeper corals were received from volunteers who were trained in years past. Some scientists believe that deeper coral, being protected somewhat from the warming surface waters, are the key to coral reef survival.

Terry told the Source that divers at TNC have “noticed some paling in some of the deeper plate corals but haven’t seen any-wide spread bleaching this year.”

When asked what she hopes BleachWatch will accomplish, she explained, “Coral bleaching is largely due to warming waters from climate change and while we, on a local level, might not be able to stop climate change by ourselves, we can monitor and track these events as they happen to determine which reefs are more or less resilient to bleaching. Then we can use this knowledge to inform further conservation efforts, like the creation of protected areas or reducing pollution or overfishing in areas that are already susceptible to bleaching so as not to compound their stress.”

The survey sheet filled out by the citizen scientists is detailed and includes instructions such as “Estimate the percent coral coverage and other observations using the BleachWatch VI Data Sheet. Record any other findings (ex.: number and types of herbivorous fishes, number and types of invertebrates, number and types of diseases, etc.) using the notes section. Take photographs at each of your five survey stations and of any important observations or organisms.”

For residents who don’t want to get into such detail but would like to report reef damage, there is a quick report section on the BleachWatch page. When you get to the “quick report” feature, pin the map where you saw the disturbance and select from a list of disturbances, including coral disease, marine debris, and anchor damage.

“We hope that, if nothing more, the program encourages community members and visitors to pay attention to what’s happening on our reefs and inspire them to get involved with conservation efforts.”
