matsumurai stayed along the shore during high tide than during low tide, it may be that this species left the shore with the ebb current and returned toward shore on the flood tide.
The adults can venture out of the cove without resisting the ebb currents. The merits of being able to move with tidal currents would be twofold: firstly H.
Under the influence of northeast winds (Figure 15(e)), after drifting some distance with the ebb current
, the oil slick moved to the southwest through passenger ferry berths and the port due to the combined effect of the wind and the flood current.
The maximum ebb current are registered along different sectors the main estuarine channel where the maximum current is about 1.5 m/s (Table 5).
In the southern Bay area, this current meets the opposite inertial ebb current of the mixed waters from the inner estuary that are extruded from the main channel.
The drift currents from the incoming waves transport sediments in a south westerly direction, creating the incipient barrier after breaking down the two-layered flow during the spring and neap tides (Chawla et al., 2008), as well as during the same tidal cycle with less saline ebb current surface and marine current flows.
In this way, the morphology of the wave fronts was modified by the ebb current and, as a consequence, also their direction of propagation.
In the Oka estuary, waves approach mainly from the northwest and force the ebb current to move to the western margin where the wave heights are smaller.
3) disappeared between July and August 2005 due to both the landward migration of the intertidal sand ridges and to the sand transport produced by the ebb currents. These processes reinforced the development of the Mundaka sand bar and returned the inlet channel to its former position close to the rocky western margin.
Since ebb currents
begin about 0.5 h after the time of high tide at the collection site, a peak in activity shortly after high tide would insure seaward transport during ebb tide.
Maximum flood currents are observed near high water elevations, and maximum ebb currents
, near low water.
Of the 36 gravid females captured traveling in ebb currents
, 35 (97%) possessed dark sponges (brown or black) containing late-stage embryos.
