A layer is a part of the ocean where the vertical gradient of water temperature, salinity, density, etc. is particularly large and can be used to separate the upper and lower layers. The word layer is not usually used alone, and there is no word in English that directly corresponds to layer. Depending on the quantity being studied, it is used as thermocline, halocline (halocline or salinocline), pycnocline, etc. These layers are formed in relation to each other, so when viewed broadly, they often seem to refer to the same layer, but strictly speaking they are not the same.

海洋中で水温・塩分・密度などの鉛直勾配が特に大きく、それを境に上層と下層に分け得るような部分を躍層という。躍層という言葉は単独では通常用いられ ず、特に英語では直接、躍層に対応する言葉がない。対象とする量に応じて、水温躍層(thermocline)、塩分躍層(halocline または salinocline)、密度躍層(pycnocline)というように用いる。これらの躍層は、たがいに関連して形成されるから、大まかに見れば同じ 層を指すように見える場合が多いが、厳密には一致しない。 (永田)
