一線天

簡介

📍 概況：東海岸極致壯闊的斷層地質奇觀，兩面垂直聳立的巨大岩壁夾出一道深邃幽暗的海底裂縫。 🤿 環境：水深 18-32m，水道兩側崖壁高聳逼近，向上仰望僅見一線天光，水流常沿著狹縫加速。 🐠 生態：峭壁兩側生長著深水海扇與海百合，深處陰影區是龍蝦群、大型巨斑與罕見海蛞蝓的隱密天堂。 ⚠️ 須知：峽谷地形容易產生沿縫急流與下降流，進入縫隙內需高度警覺免減壓時間與氣瓶殘壓。

📍 Overview: A dramatic eastern fault fracture where sheer underwater cliffs enclose a narrow corridor looking up to the sky. 🤿 Conditions: 18-32m deep. Massive vertical rock faces frame the abyss, creating accelerated currents through the chasm. 🐠 Ecology: Shaded cliffs densely packed with deep-water sea fans and crinoids; natural haven for lobsters and large groupers. ⚠️ Note: High risk of localized downcurrents inside the fissure. Strict buoyancy control and NDL monitoring are compulsory.
