Pledge to Protect: ONE°15 Marina Coral Garden Updates

Pledge to Protect: ONE°15 Marina Coral Garden Updates

Feb 28, 2019

With more than 27% of the world’s coral reefs being destroyed, ONE°15 Marina is on a mission to go green and safeguard our beautiful marine biodiversity through the launch of the ONE°15 Marina – Seakeepers Asia Coral Garden project.
In conjunction with the Tropical Marine Science Institute (TMSI) of NUS and sponsors The International SeaKeepers Society Asia, Audi Singapore and SC Global Developments, this project aims to protect the marine-eco-system in our marina and provide a natural habitat for existing sea life so that we may nurture an aquatic treasure trove for all to explore.

In this post, we would like to document and share the exciting updates and project developments through our restorative efforts.

An update on our coral fragments over a period of 7 months after transplantation!
Six new nursery frames were installed along the pontoons at Area P on 28th August 2019. As of January 2020, 95 live coral fragments remained on the nursery frames. Most coral fragments had recovered from the fragmentation process and appeared healthy.

On 31st July 2019, the team were requested by management to assist in the deployment of a “coral aggregating structure”. As of January 2020, only sediment and turf algae were observed on the structure. Below is an image of the structure at the start and six months after deployment.

ONE°15 Marina is extremely honored to have our event sponsor, Marina Technology & Construction Pte Ltd (MTC) as a part of the PACT (Plant-A-Coral-Today) Project on our 12th Anniversary. A group of divers from NUS Tropical Marine Science Institute played their part by planting corals at the Marina, in an effort to build a thriving Marine biodiversity within the waters of ONE°15 Marina Sentosa Cove.

Check out the growth of the coral fragments over a period of 3 months, what progress!

The team has also installed 6 new nursery frames along the pontoons and transferred corals of opportunity (COPs) onto the new frames to improve the health and survivorship of the coral fragments. The old frames will be repurposed as nursery tables by overturning and anchoring them to the seabed to rear more corals.

Here are some before and after photos of our coral garden, as well as a sneak peek of the coral monitoring process.

15 April 2019
Over the past few months, the TSMI team transferred over 70 coral fragments onto the new seawall, monitoring their growth and health. The overall transplant survivorship was 91.1% – most coral transplant recovered from the transplantation process and appeared healthy with visible growth, growing up to twice their initial area.

These statistics show that using marine epoxy was viable in assisting the transplation of corals at ONE°15 Marina, and that certain species such as Tubrinaria mesenterina and Goniastrea aspera are suitable for larger-scale marina transplantation.

Juvenile marine fishes such as the black eeltail catfish, kite butterflyfish, and longfin spadefish were seen seeking shelter and food at the nursery frames.

The TSMI team are currently working on the following recommendations to enhance the coral gardens

  1. Convert two wells from Boaters Bar and all six floating nursery frames into nursery tables.
  2. Reinforce and replace new metal mesh on all 3 old floating nursery frames.
  3. Install additional new six floating nursery frames based on the old metal frame structures.
  4. Diving to transfer some corals from the floating frames to temporary holding frames to assess the integrity of the old frames.
24 December 2018
We are proud to report that there has been an overall coral transplant survivor-ship of 93.2%. Most of the coral transplants have recovered from the transplantation process and appeared healthy with visible growth. The transplants increased in size by an average of 0.97 – 1.59 times.
30 November 2018
We transferred 36 coral fragments from the nursery to the seawell. In total, 80 hard coral fragments have been transplanted to the seawell area. 77 live coral transplants remained on the seawall. The total area of coral transplants was 1503.4cm2.
