| Definition | An epoxy resin-coated steel torpedo-shaped object designed to be towed alongside a moving ship at speeds of 1-12 knots. A teflon-lined tube runs through the centre of the fish and is connected to a pump on board the ship. Stabilising fins at the rear of the fish ensure that the sampling hose points forwards and that the fish maintains a roughly constant depth. The system is typically used for continuous, underway, clean sampling (e.g., trace metal studies) of near-surface waters. |
