  2. Saltstraumen - Wikipedia

    en.wikipedia.org/wiki/Saltstraumen

    The speed of this current also has a broad maximum being above six knots from two hours and forty minutes after Bodø high tide until five and a half hours before the next Bodø high tide. The behavior of the current may differ from normal due to strong winds or when more fresh water than usual is entering into the fjord from the surrounding ...

  3. Salt tide - Wikipedia

    en.wikipedia.org/wiki/Salt_tide

    Salt tide is a phenomenon in which the lower course of a river, with its low altitude with respect to the sea level, becomes salty when the discharge of the river is low during dry season, usually worsened by the result of astronomical high tide.

  4. Salt pannes and pools - Wikipedia

    en.wikipedia.org/wiki/Salt_pannes_and_pools

    Salt marsh showing salt pannes and ponds, spartina alternifolia and invasive phragmites communis in foreground. Brackish marsh panne variants occur in brackish marshes (short graminoid variant), one of the native dominant species is spike grass (Distichlis spicata), some brackish marsh pannes are dominated by the narrow-leaved cattail (Typha angustifolia) an invasive exotic species.

  5. Tide table - Wikipedia

    en.wikipedia.org/wiki/Tide_table

    Tide tables, sometimes called tide charts, are used for tidal prediction and show the daily times and levels of high and low tides, usually for a particular location. [1] Tide heights at intermediate times (between high and low water) can be approximated by using the rule of twelfths or more accurately calculated by using a published tidal ...

  6. Salt marsh - Wikipedia

    en.wikipedia.org/wiki/Salt_marsh

    Salt marsh during low tide, mean low tide, high tide and very high tide (spring tide). A coastal salt marsh in Perry, Florida, USA.. A salt marsh, saltmarsh or salting, also known as a coastal salt marsh or a tidal marsh, is a coastal ecosystem in the upper coastal intertidal zone between land and open saltwater or brackish water that is regularly flooded by the tides.

  7. Tide - Wikipedia

    en.wikipedia.org/wiki/Tide

    Tide flow information is most commonly seen on nautical charts, presented as a table of flow speeds and bearings at hourly intervals, with separate tables for spring and neap tides. The timing is relative to high water at some harbour where the tidal behaviour is similar in pattern, though it may be far away.

  8. Cook Inlet - Wikipedia

    en.wikipedia.org/wiki/Cook_Inlet

    These, along with the tides, provide a challenge to ships navigating through the waters. [10] The strong tides create powerful rip tides and bore tides which are sometimes among the largest in the world. [11] Tidal bores occur within the inlet, and especially Turnagain Arm, almost daily, but are usually too small to notice. Large bores tend to ...

  9. Chart datum - Wikipedia

    en.wikipedia.org/wiki/Chart_datum

    A chart datum is the water level surface serving as origin of depths displayed on a nautical chart and for reporting and predicting tide heights. A chart datum is generally derived from some tidal phase, in which case it is also known as a tidal datum. [1] Common chart datums are lowest astronomical tide (LAT) [1] and mean lower low water (MLLW).
