Russia's state-owned Tass news agency said the ships are "performing long-distance voyage missions in various parts of the World Ocean" in an attempt "to demonstrate the Russian Navy's flag and provide for naval presence in operational areas of the long-distance oceanic zone".
In the oceanic zone of northwestern Mexico (including the Gulf of California), paralarval distribution has been associated with the seasonal and interannual advance and retreat of latitudinal distributions of water masses, the northward transport of warm waters by El Nino-Southern Oscillation, the convergence and front formation of surface water masses, retention through mesoscale eddies, and with adult spawning habitats (Granados-Amores et al., 2010; De Silva-Davila et al., 2013; Staaf et al., 2013; Sanchez-Velasco et al., 2016).
1), were distributed along the shelf and continental margin of the Gulf of Tehuantepec and in the oceanic zone of transect 1 (Fig.
According to the results obtained, there is intense reproductive activity of squid from May to June in the Gulf of Tehuantepec and the adjacent oceanic zone, with spawning and/or hatching grounds preferentially located in the high Chl-a concentration areas of cyclonic eddies, front zones and coastal areas with high primary production.
The large abundance of small paralarvae over the shelf indicates that Dosidicus gigas and Sthenoteuthis oualaniensis (SD complex) spawned in both the oceanic zone and on the continental shelf of the Gulf of Tehuantepec, as has been reported for other areas (Nigmatullin et al., 2001; Jereb & Roper, 2010).
The paralarvae trapped in the center of the anticyclonic eddies can be transported through advection toward the oceanic zone and to the southwest out of the coast.
Marine Biology students tend to guess, "It lives in the ocean," and through discussion we decide on the most probable oceanic zone (e.g., intertidal).
Medium-sized specimens were found in the oceanic zone and large specimens with a high ratio of maturity were found in the coastal zone during winter.
gigas in the oceanic zone off Chilean HCS do not migrate to coastal waters and mature at small sizes (56-63 cm ML; Liu et al., 2010, see Fig.
gigas, assuming that in Chilean waters the squid is reproducing year-round and has two pronounced spawning peaks (winter and summer) that occur in oceanic zones (Clarke & Paliza, 2000; Gonzalez & Chong, 2006; Zuniga et al., 2008; Liu et al, 2010).
Project 11356 frigates are designed to deliver strikes against enemy surface ships and submarines in the close-in and oceanic zones and fight air targets.
The Indian technocrats are expecting to increase the monitoring capacity of oceanic zones from the Oceansat-2.
