Definition

1. Noun:
   • The water column that is neither at the surface nor near the ocean/lake floor: "Mid-water" refers to the pelagic zone of a body of water that is significantly below the surface and significantly above the bottom substrate. It is the open water environment between the surface layer and the benthic (bottom) layer.

Usage

• "Mid-water" is a technical term used primarily in marine biology, oceanography, and fishing contexts to describe a specific ecological habitat.
• It is often used attributively (like an adjective) before another noun to describe things located in or pertaining to this zone (e.g., mid-water trawl, mid-water species).
• Example:

Examples

• Midwater (adj): A common alternative spelling used as a single word, especially in compound terms (e.g., midwater fishes).
