The dominant westward palaeocurrent pattern, as shown by the Panjgur succession (Kassi et al.,2003), is parallel to the regional trend and trench axis, which is characteristic of trenches where abyssal plains
are incorporated into the accretionary wedges (Dickinson, 1982; Nilsen and Zuffa, 1982; De Roza et al., 1986; Lash, 1986,1987).
The flat abyssal plains
of soft silt haven't managed to avoid cable troubles either.
(2006) for carbonate rocks extracted from the Chapopote Knoll in the abyssal plain
near the Campeche Bank in the southeastern Gulf of Mexico, described as a wackestone micrite with [delta][sup.13]C ranging between -23.0 and -23.5%.
In 2007, a total of 6900 km of seismic data were collected over the Sohm Abyssal Plain
Deep structure of the ocean-continent transition in the southern Iberia Abyssal Plain
from seismic refraction profiles: Ocean Drilling Programme (Legs 149 and 173) transect.
The results show that cyclonic features are depicted in the Tyrrhenian Sea, the Abyssal Plain
and the Ligurian Sea, and anticyclonic in the Algiers Basin and the Sardiniono-Balearic Pass.
There are just five manned submarines in the world that can reach the abyssal plain
and less than one per cent of it has been explored.
The northern Newfoundland Basin (NB) is the conjugate to the Iberia Abyssal Plain
. Available geophysical data suggest that the Newfoundland Basin contains a zone approximately 150 kilometers wide of thinned continental crust separating known Grand Banks continental crust from known oceanic crust seaward of a mid-Cretaceous period (about 118 million years ago) isochron, a magnetic anomaly known as MO.
As a result, the observatory network spans both continental and oceanic crust, extending from the coast across the shelf, down the continental slope (including a submarine canyon), across the abyssal plain
, to span the mid-ocean ridge (Fig.
Therefore, ODP Leg 173 enlarged the information on the sediment cover of the continental and oceanic basement in the Iberian Abyssal Plain
(IAP) by recording the depositional sequences from the late Jurassic (Tithonian) to early Tertiary (Eocene), the most important stratigraphic interval in the structural development of the Iberian plate.
The specimen was a female, carapace length (cl) 23.3 mm, taken by a 25-foot otter trawl on an abyssal plain
off Baja California, Mexico (31[degrees]20'N, 120[degrees]8'W), 3707-3806 m, 23 March 1970, R/V Melville, SIO sta.
Down on the Abyssal Plain
, visibility is so bad, and mating therefore so difficult, that one male - taking no chances - sticks himself to the female so that they are, literally, glued at the hip.
