We could not do anything more or marine creature, weather crisis or protect our coastline. But keep going to folllow Dr. Jauwen Chan as .....
The temperature decresed under seawater recently, 3 or 4 meters deep around Betou park, let's read after Dr. Jauwen Chen.
2020年除了肺炎疫情, 對於愛海洋的我們來說,
最嚴重的莫過於珊瑚白化了。
海下一片白茫茫,彷彿被白雪覆蓋似的......
令人震驚與不捨。
因此, 我們將於10月21日(三)19:30於三創生活園區
舉辦「追逐珊瑚Chasing Coral」 影片放映會,
並於映後特別邀請中研院 陳昭倫博士來與我們分享台灣今年的珊瑚白化狀況~ 想更了解台灣的海洋嗎?
關心環境愛惜珊瑚的朋友,請絕對不要錯過囉!!

【20200926台灣海洋國土珊瑚大白化監測】-走向死亡的珊瑚
雖然東北季風帶著寒意在台北的天空盤旋,從墾丁和綠島研究團隊進行全台第三波珊瑚白化監測的工作也已進尾聲。逐漸降溫的海水給了毛狀藻大量爆發的機會,也為已死亡的珊瑚骨骼穿上黑色喪服。
【20200919台灣海洋國土珊瑚大白化監測】-東北角鼻頭公園
終於開始降溫了!在鼻頭公園3-4米水深測得的溫度為28C。希望接下來東北季風能夠讓北部與東北角海域的水溫持續降溫。
只是水下觀察並沒有帶來讓人太多興奮的消息。如之前的預測,鼻頭海域白化的珊瑚已經進入死亡階段。大型的微孔珊瑚呈現組織潰爛的病程,毛狀藻開始入侵。管孔珊瑚的珊瑚蟲不在外伸,也開始潰爛。細枝鹿角珊瑚已明顯部分死亡,毛狀藻開始佔據群體。而以珊瑚為主食的白結螺依然活躍。
稍微讓人欣慰的是萼形柱珊瑚的顏色已逐漸回復,而繩紋珊瑚科的菊珊瑚、角菊珊瑚、圓菊珊瑚等的組織還在,希望降溫後,共生藻群聚能夠回復。
Seawater temperature finally starts to decrease. The temperature was detected around 28 degree Celsius
at 3 to 4 meter deep in Bitou Park. Hopefully the Northeast monsoon can continue to bring down seawater temperature in the Northern and Northeastern Taiwan.
There is no exciting news from our underwater observation of coral bleaching. Bleached corals start to decease in the Bitou Park. Tissue tissue necrosis is observed in the large Porites bommies and turf algae start to grow on the whitening skeleton. Gonipora polyps are no longer extending and part of tissues also show necrosis. Pocillopora colonies are obviously dead and covered by turf algae.
Nevertheless, we observe Stylophora colonies start to regain colour, and Merulinidae, such as Dipsastraea, Favites, and Astrea, although look white, tissues remain intact. Hopefully, they could recover their symbiotic algae after seawater temperature return to normal.
