Photography of the Ocean Bottom*

VideoSolo, an autonomous video system for high-frequency monitoring of aquatic biota, applied to coral reef fishes in the Glorioso Islands (SWIO)

“…The first automatic surface-deployed underwater cameras triggered by a bottom-contact switch were made in the 1940s (Ewing et al, 1946). The photographs taken showed objects on the ocean bottom in their natural environment.…”

The Spherical Current Meter

“…1 The pendulum method of measuring sea current has previously been carried out by suspending from a boat which is anchored or from a frame which is set on the sea bottom. (EWING et al, 1946;SWALLOW et al, 1957;SASAKI et al, 1962;PRATT, 1963) In these cases, the measuring period was not so long and the long wave interfered with the measuring accuracy, or it could measure only near the sea bottom. The floating method employed.…”

Biological and Geological Observations on the First Photographs of the Arctic Ocean Deep‐sea Floor1

“…The camera was a modification of the Ewing suspended automatic camera (Ewing et al 1946 Ridge; H, the Lomonosov Ridge, and C, the Alpha Rise. The photographs were taken on the Alpha Rise.…”

“…The camera was a modification of the Ewing suspended automatic camera (Ewing et al 1946 GMT;20 December, 1957. This location is also on the south flank of the newly discovered Alpha Rise (Anon.…”
