Morro Rock is a 581-foot volcanic plug located just offshore from Morro Bay, at the entrance to Morro Bay Harbor. The Morro Bay SMRMA includes the area below mean high tide within Morro Bay east of the Morro Bay entrance breakwater and west of longitude 120° 50.34′ W. [2]
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 ...
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).
A bathymetric chart is a type of isarithmic map that depicts the submerged bathymetry and physiographic features of ocean and sea bottoms. [1] Their primary purpose is to provide detailed depth contours of ocean topography as well as provide the size, shape and distribution of underwater features.
The chart datum varies according to the standard used by each national Hydrographic Office. In general, the trend is towards using lowest astronomical tide (LAT), the lowest tide predicted in the full tidal cycle, but in non-tidal areas and some tidal areas Mean Sea Level (MSL) is used.
Morro Bay (Morro, Spanish for "Hill") [9] [10] [11] is a seaside city in San Luis Obispo County, California, United States. Located on the Central Coast of California , the city population was 10,757 as of the 2020 census , up from 10,234 at the 2010 census .
High surf pounded the San Luis Obispo Coast on Thursday morning, causing multiple water rescues, flooding and closures. A pickup truck overturned in Arroyo Grande Creek, and RVs were washed into ...
Tide range is the vertical distance between the highest high tide and lowest low tide. The size of the lunar tide compared to the solar tide (which comes once every 12 hours) is generally about 2 to 1, but the actual proportion along any particular shore depends on the location, orientation, and shape of the local bay or estuary.
