Hawaii’s ban on “reef-unfriendly” sunscreen

by Austin Yeung 2017-02-06

Symbiosis Sea TurtleJanuary 20th, US Senator Will Espero proposed a bill banning sunscreens containing oxybenzone and octinoxate: chemicals that have been found to be harmful to Hawaii’s reefs. The ban, if successful, helps to protect Hawaiian reefs and maintain the heavy tourism economy the coral reefs attract. The ban has also been noticed by other regions that rely on reefs, including Palau and the British Virgin Islands.

Research in 2016 by the Haereticus Environmental Laboratory in Clifford, Virginia has found octinoxate to stunt the growth of baby corals and oxybenzone to be toxic. These chemicals have been found to cause coral bleaching in the lab as well as in the wild. Field data show that levels of oxybenzone contamination were at 4,000 parts per trillion (ppt) along the most popular beaches off the coast of Maui. With 9 million visitors a year, oxybenzone and octinoxate sunscreen pollution pose a serious environmental hazard.

However, this bill is only a small step in protecting Hawaii’s reefs. Larger concerns of overfishing, coastal runoff, and pollution still pose serious concerns. We should take this step to help promote visitor awareness for Hawaii’s reefs.

I’m also pleased to report that the ‘Reef Perspectives’ article I wrote on coral reef conservation was accepted for publication in this same Dec 2016 issue.

Expedition to Palau

by Austin Yeung 2016-07-26

Six months and a few hundred diving photos later, I returned to Palau. This time, the purpose of travel was entirely different. Instead of vacationing in Palau, I was doing field work – coral experiments.  Marine biologist Prof. Palumbi and Megan Morikawa from Stanford University were doing baseline data collection in Palau. Amazingly, I was fortunate enough to be able to join them on this research expedition. Along with my friend Sebastian, another avid diver and photographer, I was introduced to sample and data collection in the ocean. By using data loggers, we recorded temperatures of the patch reefs in the area. A critical aspect of the experiment was to navigate the seas and find the locations at which the data loggers were first placed. I found this to be a very valuable learning experience as I was taught how to use a satellite GPS and use it to navigate the waters. It was fun, it was relaxing, and it was educational.

As you can imagine, doing research work in an environment like that of Palau, it’s hard not to become distracted by the beauty of the environment. With our underwater cameras, Sebastian and I were able to capture breathtaking photos of underwater life. On one particular occasion, Prof. Palumbi discovered a lionrock: a rock that sheltered lionfish. By using still shots with the GoPro, I was able to record the movements of a spectacular baby lionfish and its two parents. It’s the little things that we saw during our research expedition that really attracts me to this particular type of research. It’s the combination of seeing wildlife beauty and the research work around it that interests me. This is why I enjoy marine biology.

Summer internship at HKU

by Austin Yeung 2016-07-17

I am back to Hong Kong working as a summer intern with Prof. Dave Baker at the University of Hong Kong. This year, I got to work with Vicky and others in a number of projects within the new Baker Lab on the HKU main campus. Vicky taught me some basic forensic lab skills where I am learning how to extract DNA. I also met Ashley, another intern working at HKU this summer, in which we both experimented with the 3D scanner and became mini ‘experts’ on it.

It has been a great deal of fun and learning.

ICRS 2016 opens in Hawaii

ICRS2016

by Austin Yeung  2016-06-22

The 13th International Coral Reef Symposium (ICRS) opens in Honolulu, Hawaii, and will run from Jun 19-24, 2016.

I am very excited to join more than 2,500 attendees from 97 nations at this event.  Since attending the 3rd Asia Pacific Coral Reef Symposium (2014APCRS) at Kenting, Taiwan in June, 2014, I’ve been looking forward to participating in the 13th ICRS, where I will be making a poster presentation under the supervision of Dr. Baker.

Happy to be here in Honolulu!

An internship at SWIMS

My summer internship at SWIMS

Austin at SWIMS 2015by Austin Yeung 2015-08-13

Just had an exciting ‘two-week’ summer internship at The Swire Institute of Marine Science (SWIMS) in Hong Kong.  Many thanks to Prof. Baker for allowing me to be in his lab – which is really ‘everywhere’ — from the work bench within SWIMS at Cape D’Aguilar, where I got to work with Phil to quantify photo effects on coral/algae symbiosis, to ‘sitting in’ on department seminars with the folks from the Baker Lab on the HKU main campus, to ‘exploring and snorkeling’ Lantau and Nine Pins Islands, where Nico led us in surveying and collecting coral specimens for “paleoecological studies.”

Exciting projects and truly fun and smart people!  I learned a lot.

pH, nitrate and phosphate levels in Hong Kong Waters

by Austin Yeung 2015-08-09

Recently, with the help of my father, I collected water samples from Kaneoke Bay, Hawaii and various parts of Hong Kong.  My goal is to compare the pH, nitrate and phosphate levels of these sea water samples, using aquarium-type test agents purchased from the aquarium store in Hong Kong.

The results are interesting.  The Shek O sample has highest pH whereas the Kaneohe Bay sample has medium pH and the Gold Coast sample has the lowest pH value. For phosphate, the Kaneohe Bay sample has the lowest reading, whereas the Gold Coast sample again has the highest.

Summer course at HIMB

by Austin Yeung 2015-07-24

I had a blast with my marine biology class at the Hawai’i Institute of Marine Biology (HIMB), a world-renowned research institute at the University of Hawai’i (UH) at Manoa, this summer.

Located on Moku o Lo’e (Coconut Island) in Kane‘ohe Bay, HIMB is the only marine research facilities that are built on a coral reef and an island by itself.  It provides excellent research and learning opportunities located just 15 miles from the main UH campus and downtown Honolulu.

I took this marine science summer course in July, 2015 at HIMB on Coconut Island. It’s a one week course, with a class of 20 high school students. If interested in more, please view my video.

Wonderful experience!
