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 ...
An invasive species is a species not native to a particular location which can spread to a degree that causes damage to the environment, human economy or human health. [19] In 2008, Molnar et al. documented the pathways of hundreds of marine invasive species and found shipping was the dominant mechanism for the transfer of invasive species in ...
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 ]
The effects of climate change on plant biodiversity can be predicted by using various models, for example bioclimatic models. [5] [6] Habitats may change due to climate change. This can cause non-native plants and pests to impact native vegetation diversity. [7] Therefore, the native vegetation may become more vulnerable to damage. [8]
Phytotoxicity describes any adverse effects on plant growth, physiology, or metabolism caused by a chemical substance, such as high levels of fertilizers, herbicides, heavy metals, or nanoparticles. [1] General phytotoxic effects include altered plant metabolism, growth inhibition, or plant death. [2]
Cyanobacteria (blue-green algae) bloom on Lake Erie (United States) in 2009. These kinds of algae can cause harmful algal bloom. A harmful algal bloom (HAB), or excessive algae growth, sometimes called a red tide in marine environments, is an algal bloom that causes negative impacts to other organisms by production of natural algae-produced toxins, water deoxygenation, mechanical damage to ...
Foam depopulation was developed in 2006 in response to a 2004 outbreak of H7N2. [8] It received conditional approval the same year in the US by the USDA-APHIS. [9]In the 2015 H5N2 outbreak in the US, foaming was the primary method used to kill poultry en masse with it employed at 66% of locations. [10]
