In recent years the Mosquito lagoon has experienced several algal blooms, called "brown tides", that have resulted in extensive fish kills. The species of alga thought to be primarily responsible for the blooms, Aureoumbra lagunensis, was first detected in the lagoon in 2005. Blooms causing fish kills have occurred in the lagoon in 2012, 2016 ...
Cupy the first light station on Browns Point, erected in 1887, consisted of a white light lens lantern on a white post that stood 12 feet (3.7 m) above sea level and 50 yards from the low tide shoreline. [4] A wood-frame lighthouse and separate keepers cottage were built in 1901. The current lighthouse was built in 1933 and automated in 1963. [5]
An amphidromic point, also called a tidal node, is a geographical location where there is little or no difference in sea height between high tide and low tide; it has zero tidal amplitude for one harmonic constituent of the tide. [2]
These tide pools feature large lava rock formations filled with colorful saltwater pools. [1] The site was formed during volcanic activity about 5,000 years ago. [2] A large lava flow went down the northeast side of the island into the ocean, forming the Flat Point peninsula as it cooled. [3] Today the Flat Point Tide Pools are home to diverse ...
A good example would be Brown's, which commenced in 1877, and is still produced annually, its early 20th-century subtitle being "Harbour and Dock Guide and Advertiser and Daily Tide Tables". This combination of trade advertising, and information "by permission... of the Hydrographic Department of the Admiralty " provided a useful compendium of ...
The water stops rising, reaching a local maximum called high tide. Sea level falls over several hours, revealing the intertidal zone; ebb tide. Oscillating currents produced by tides are known as tidal streams or tidal currents. The moment that the tidal current ceases is called slack water or slack tide. The tide then reverses direction and is ...

Tidal range is the difference in height between high tide and low tide. Tides are the rise and fall of sea levels caused by gravitational forces exerted by the Moon and Sun, by Earth's rotation and by centrifugal force caused by Earth's progression around the Earth-Moon barycenter. Tidal range depends on time and location.
