Sea foam washed up or blown onto a beach. Sea foam, ocean foam, beach foam, or spume is a type of foam created by the agitation of seawater, particularly when it contains higher concentrations of dissolved organic matter (including proteins, lignins, and lipids) derived from sources such as the offshore breakdown of algal blooms.

The soft, white, earthy mineral from Långbanshyttan, in Värmland, Sweden, known as aphrodite (Greek: sea foam), is closely related to sepiolite. [7] [23] In construction, sepiolite can be used in lime mortars as water reservoir. [24] Processes for bacterial transformation based on the Yoshida effect can utilize sepiolite as an acicular ...
It consists of a long train of narrow-band upsweeping sounds of several seconds in duration each. The source level is high enough to be recorded throughout the Pacific. The sound appears to be seasonal, generally reaching peaks in spring and autumn, but it is unclear whether this is due to changes in the source or seasonal changes in the ...
The click-like sounds, similar to the popping of popcorn, are emitted at a volume similar to human speech, but at high frequencies, beyond the hearing range of the human ear. Source: Tel Aviv ...
However, human activity has disrupted this soundscape, largely drowning out sounds organisms depend on for mating, warding off predators, and travel. Ship and boat propellers and engines, industrial fishing, coastal construction, oil drilling, seismic surveys, warfare, sea-bed mining and sonar-based navigation have all introduced noise ...
Limonium perezii is a species of Limonium known by the common names Perez's sea lavender and seafoam statice. It is also known as simply statice (reflecting the former name of the genus), sea lavender or marsh rosemary (common names for the genus). It is native to the coasts of the Canary Islands but are widely used in gardens throughout the world.
The historical background of natural sounds as they have come to be defined, begins with the recording of a single bird, by Ludwig Koch, as early as 1889.Koch's efforts in the late 19th and early 20th centuries set the stage for the universal audio capture model of single-species—primarily birds at the outset—that subsumed all others during the first half of the 20th century and well into ...
DOCs derived from decomposing algae and other plants in water courses are one important source, however DOCs derived from bogs and wetlands are very important. Brown-water streams with brown water contain high levels of DOC and much of the foam forms after snowmelt, after prolonged heavy rains and in autumn. [ 3 ]
