...是牠們在這些監察點的特別出沒模式。 在 2018 至 2021 年的四個年度期間，中華白海豚及江豚的發聲記錄 (C-POD DPMs) 與船上調查的參數有明顯的關聯，但其相關性並不強烈、亦並非在每一個 監察點穩定地出現。由於發聲記錄及船上調查參數均與海豚的出現程度相關，所 以呈現明顯的關聯並非令人意外，但較弱的相關性卻可能源於兩種研究方法的基 本差別，因為船上調查方法雖覆蓋大片海域但卻在每一處停留很少時間，水底聲 7 音監察方法雖定點覆蓋一小片海域但卻持續不分晝夜搜集數據。為要兩種研究方 法搜集的數據達致更緊密的關聯，必須要投放更多的 C-POD，以更大幅度覆蓋船 上調查的研究範圍。 將 C...

...石角附近的龍鼓水 道。由於這些移動路線的存在對海豚甚為重要，因此必須加以研究，並以防將來 在大嶼山附近的一些工程影響白海豚繼續使用這些移動通道。 在 2012-13 年間，研究員在大嶼山一帶水域的水底聲音監察站，共錄取了 101 個、合共 10.16 小時的水底聲音片段。一項針對海豚哨聲的研究，利用了 2010-211 年間搜集的 13 個海豚發聲片段，共分析了 1,410 個哨聲樣本；該研究共辨別出 27 種白海豚哨聲，足證香港的中華白海豚會發出眾多不同的聲音，而其哨聲的 輪廓比其他地方的駝背豚種群更為複雜。未來的研究將集中分析白海豚哨聲，會 否因不同程度的人為噪音所影響而有所改變。 一項嶄...
