When Science and Art Collide: Sci-Art Communication
I am currently working with a brilliant innovative artist, Jocelyn Ng, who has transformed me into one of my experiments to help communicate impacts we have on our reefs.
Check out her work amazing work.
Exhibit coming soon March 2019.
Corals are adapting to survive warmer waters
As our planet and oceans warm, researchers question whether corals can adjust. To attempt to answer this question, we replicated the landmark study conducted in the 1970s to determine if there has been any change to coral temperature tolerances in the last half century. In the summer of 2017, we replicated the original experiment using the identical experimental system, methodology, location, species of coral, and even one of the original researchers, Dr. Steve Coles. This provided a very unique opportunity to evaluate whether coral bleaching thresholds have changed over the past 50 years.
Differences between the two experiments were dramatic. Results show a substantial increase in coral temperature tolerance. In the three species of Hawaiian corals retested, bleaching occurred later, with higher survivorship and growth rates than corals in 1970.
The Hawaiian Koʻa Card
Monitoring coral health through color - Coming soon 2019
We are currently conducting our last set of experiments to validate the Hawaiian Koʻa Color Card. The goal of this project was to provide a tool for resource managers, scientists, students, and the community to monitor the changes that are occurring on our reefs. Each color is linked to the physiological state and health of the coral. We hope to have a final product out by summer 2019.
Investigating changes in coral reef biodiversity
Watch the episode of Voice of the Sea with Dr. Kanesa Seraphin where I speak with her about understanding ocean warming and acidification impacts of coral reef biodiversity using Autonomous Reef Monitoring Structures (ARMS).
Another great year of Field problems in Marine Biology!
Great job team!
Field Problems in Marine Biology is an intensive 4-week field course where students live and work at the Hawai’i Institute of Marine Biology. I help equip them with the skills they need to become the future resource managers.
The 2018 cohort investigated changes in the abundance and distribution of Fungia scutaria (mushroom coral) over the past 18 years and what natural and anthropogenic factors have driven those changes.
I was very fortunate to speak with the faculty and students at Santa Monica College about the impacts we have on our reefs!
Warmer seawater temperatures are negatively affecting coral reefs in Hawaiʻi—and across the globe - and are tied to the drastic increases in global carbon emissions over the past several decades. During the recent global bleaching event, surveys were conducted inside Hanauma Bay Nature Preserve, to assess the impact of these warmer waters on this protected coral reef ecosystem. Approximately half of the corals bleached and despite the lack of local influences (e.g., sedimentation, fishing and harvesting pressure), some coral mortality (~10%) occurred. Continued exposure to thermal stress can lead to reduced reef complexity, coral cover, and biodiversity. Global climate change poses a direct threat to the biological sustainability of the protected reefs of Hanauma Bay Nature Preserve and a clear economic threat for the state of Hawaiʻi.
