Some food dispensed in aquaculture operations — especially open water cages — is inevitably not consumed and together with faeces the nutrients released into the surrounding water can cause oxygen depletion and potentially lead to algal blooms.

Putting into practice techniques that keep contaminants like manure, phosphorus and pesticides — as well as road salt — from running off the land into creeks and streams and leading to bigger problems like algal blooms, bacteria proliferation and other water quality problems.

In summer, melting sea ice releases nutrients into the water, which triggers vast algal blooms.

Fishermen unhappy, scientists baffled The algal blooms are despised by many anglers in eastern Canada, and many have poured money into research.

Illuminating the scope of the problem, a set of maps shows past algal blooms in U.S. coastal waters, and a short essay delves into why the number of blooms seems to be rising — better surveillance and nutrient - laden pollution are suspected.

For years scientists have known that nitrogen and phosphorus, which commonly enter freshwater lakes in chemical fertilizers, play a role in eutrophication — the process by which algal blooms, turbidity, and oxygen deficiencies turn a lake into a dead zone, largely devoid of animal life.

Nutrients would pour down off the increasingly denuded land into the sea, triggering massive algal blooms, which would exhaust the water of oxygen and threaten fish.

The problem: Overflow and sprayed waste can find their way into local wetlands, where fecal matter triggers algal blooms that choke out other aquatic life.

The outcome: algal blooms so massive that ecosystems turn into dead zones, resource - poor realms inhospitable to other life.

I'm quite intrigued by their one about manufacturing urea to feed into the oceans to seed algal blooms, which somewhat goes against what I've read about the problems we're storing up synthesising nitrogen fertilizers.

The plants don't recover enough nutrients from the sludge, so leftover phosphorus and nitrogen trickles into the water, helping to cause algal blooms.

And excess nitrogen fertilizer applied to the fields of feed corn grown to satisfy the world's livestock runs off into streams and rivers, sometimes flowing to coastal waters where it creates large algal blooms and low - oxygen «dead zones» where fish can not survive.

During that period, tons of excess nitrogen and phosphorus entered the Mississippi River Basin and drained into the Gulf of Mexico, where the large influx of nutrients has triggered huge algal blooms.

In addition, DOC can influence algal blooms, phytoplankton productivity, and carbon sequestration in coastal waters, so understanding fluxes in DOC transport into the ocean is critical for evaluating its effects on coastal food webs.

Dead zones form when excessive amounts of nitrogen and phosphorous wash into waterways and spur algal blooms, depleting the water of oxygen and killing fish, shrimp, and other marine life.
