Activities 活動集
2024 March 3-16 Research cruise NOR1-068 Taiwan GEOTRACES
We sailed along the 21N and to 130E Weste Pacific Ocean. Our deepest collection depth is 5450m, a record breaking for Taiwan's clean seawater sampling system! Our team is responsible for anthropogenic 236U and 14C ocean tracer and persistent pollutant PAHs.
沿著北緯21度，一路向東，在遠離台灣600海浬遠的西太平洋採水，我們研究室探討的是人造核種鈾236, 碳14還有人造有機污染物的研究。
2023 July 29-August 8 R/V Thompson cruise #421
Tina visited my Ph.D. study sites again. We used remotely operated vehicle (ROV) JASON to assist sampling of the warm fluid (65°C) flowing in the rock beneath the marine sediment.
時隔10年，再次到博士研究時的海域進行採樣與探測，利用遠端遙控潛水艇到2600m深的海床上，把下方岩層中的熱泉水打上來，進行甲烷的同位素分析。
2023 Sep 16-21 HOT cruise #344
The world's most maintained ocean time-series station ALOHA is a must-visit place for Tina. Luckily, our proposal for collection seawater samples for anthropogenic ocean tracer 236U research was approved and we joined HOT cruise #344 to Station ALOHA for sampling. Former student Yu-Chen joined the cruise with me. We had a great time together.
世界上最完整資料收集時間最長的海洋時間序列站就在夏威夷的ALOHA測站，每個月大家不辭辛勞的採樣，每次五天的航次，要進行各種樣品的採集，回港後再到陸地的實驗室進行各種分析，這些寶貴的資料，讓大家更清楚海洋的變動。能親自參與其中一個航次，真的是夢想成真！

2022 Lanyu coral coring (8/3-6) Taiwan 蘭嶼珊瑚岩芯採集
Two corals were drilled near the Longmen port 於龍門港鑽了兩根珊瑚岩芯
Seawater samples also collected and filtered 海水樣品採集並過濾
Organic matter on/in the coral cores removed by soaking corals in hydrogen peroxide for several days 利用雙氧水浸泡多日去除有機物質
MRI scans of the coral cores to guide us which angle is the best to slice the core into two halves. 珊瑚岩芯的斷層掃描得知內部構造，協助選擇最佳的對剖角度
Coral cores record of the seawater compositions in the past. 珊瑚是偉大的時間紀錄器， 可以告知過去海水的變動情形。
2022 Goldschmidt Conference (7/10-15) Honolulu, Hawaii, U.S.A.
戈爾德施密特國際地球化學會議–夏威夷檀香山
Tina gave an oral presentation of our new method.
Jemmy had a poster presentation and a 3-min flash talk.
We had attracted quite some audiences.
Visited University of Hawaii's Marine Center.
We went hiking and visited the beaches.
2022 Taiwan Geosciences Assembly 臺灣地球科學聯合學術研討會
Tina gave an oral presentation of coral reef water chemistry.
Jemmy gave a poster presentation about the 236U-14C dual tracer study for the northern Luzon Strait paleo current study. He WON the BEST STUDENT PRESENTATION AWARD. Bravo!!
Karen (undergraduate student) gave a poster presentation. She received a lot of compliments for her organization skill. Nice job!
2022 Coral spawning field sampling (4/15-26) Kenting National Park, Taiwan
Massive coral spawning is predicted to occur on the Chinese sea goddess', Mazu's, birthday on Chinese Lunar calendar March 23rd.
Shallow water (<5m) coral spawned consecutively for five nights.
Egg bundles released by different corals were collected.
The 13C and 15N isotopic compositions will be analyzed.
2022 Estuary seagrass bed respiration (1/18-23) measurement with IONTU Benthic Chamber Haiko, Pingtung, Taiwan
Day-night variation
Fresh water input
Exchange from below at the 1.5 m site, near rocky basement makes the sediment likely more permeable
Get ourselves familiar with various sampling sites in Nanwan Bay
