Maintenance Performed on Marine Meteorological Moorings

Date: October 15, 2009

Though disrupted by the typhoons Ketsana, Parma, and Melor, Taiwan Ocean Research Institute's (TORI's) maintenance efforts on three sets of marine meteorological moorings finally saw completion between on Oct. 9, 2009. The systems, deployed 600km away from the southeast coast of Taiwan, are currently functioning smoothly. Maintenance was carried out with help from US research vessel Roger Revelle. TORI deployed the moorings in March, 2009 under the assistance of US research vessel Kilo Moana, in compliance with an integrated National Science Council (NSC) program under the NSC Ocean Science Program Panel, called "Typhoons in the Northwest Pacific and Its Marginal Seas—Research on Air-sea Interactions and Internal Waves." The deployed systems gather meteorological data, including temperature, atmospheric pressure, relative humidity, wind direction and speed, solar radiation, as well as the ocean surface temperature, up to 500m deep. Data collected from the air-sea boundary layer are transmitted via iridium satellite every six hours to TORI. The nearly real-time data are then processed and displayed on the TORI website: http://mom.tori.org.tw/oppo/moor.php and made ready for exchange with the Central Weather Bureau.
Two CODAR Systems Complete with Testing

Date: October 15, 2009

Two Coastal Ocean Dynamics Application Radar (CODAR) systems underwent installation and testing between Sep. 28 and Oct. 2, 2009. The radars are located respectively at Luye and Xiaoyeliu. The transmitting and receiving antennas were installed and connected to the respective mainframe rooms. Antenna pattern measurement tests and flow velocity vector synthesization tests were also carried out.

Despite harsh weather and road conditions, factory technicians, staff from domestic professional instrument companies, and scholars managed to collaboratively complete the installation of the two radars on Oct. 2. The antenna at Xiaoyeliu were temporarily removed due to the potential damage of in-coming Typhoon Parma on the same day, but reinstalled three days later for the flow velocity vector synthesization tests (see image). Discussions afterwards suggest that further adjustments in the radars' parameters be made. Taiwan Ocean Research Institute (TORI) foresees a briefing in mid-December to report on the primary test results. The briefing is thus scheduled so that the academia may incorporate the use of CODAR data in their National Science Council research projects, to be submitted by the end of the year.

Evaluation of Drift Sand Sedimentation at Xingda Harbor

Date: July 20, 2009

To ensure the navigational safety of research vessels at Xingda Harbor, Taiwan Ocean Research Institute (TORI) has commissioned a study to evaluate the port's waterway and berth area water depth. Vasty Engineering Consultants was commissioned in July, 2009 to conduct the study on the TORI headquarters-to-be. The study will monitor the port's water depths and landforms, clarify the influence of monsoons and typhoons on sedimentation, and provide maintenance estimations.

Three bouts of evaluation activities have been scheduled for both the inner harbor and the open sea. The first, to be performed in spring after the winter monsoon subsides, taking waves and tides into consideration, should highlight the primary movements of the drift sands. The second, to take place after the departure of a typhoon potential of causing the greatest impact on the distribution of drift sands in the port, will bring light into the possible effects of a single typhoon. The third, scheduled for October, shall conclude the degree of drift-sand changes caused by monsoons and typhoons over the course of one year. TORI will be setting up its headquarters at Xingda Harbor, located in Kaohsiung, with a branch elsewhere. This has been decided with official approval from the National Science Council (NSC). The mid-term report of this study has been handed in by the end of August, 2009. A final version of the harbor's evaluation report will be submitted by Nov. 25 of the same year.

Lanyu Coral Reefs Real-time Imaging System Update

Date: September 15, 2009

Tests on the Lanyu coral reefs real-time imaging system saw completion on Sep. 15, 2009, concluding the construction of the project. Circuit damages caused by Typhoon Morakot in early August, 2009 have been repaired, though the maintenance team continues to seek an appropriate timing to reinstall the underwater lens, retrieved due to the approach of Typhoon Parma. Additional plans are made to fix lightening protectors to land equipment and to proceed with basic underwater reinforcement tasks. The observation system is capable of transmitting real-time images of the coral reefs and fish ecology back to the server on-shore, then on to Taiwan via broadband internet connection. The precious images will be accessible to both the academia and the public in due time. Also, since much of the coral reefs located within the observation area happen to have been damaged by strong currents, the system will coincidentally be able to record the full recuperating process of the corals in the region.
