US military — polluting Hawaii’s water supply… and denying it

The US military is polluting Hawaii’s water supply – and denying it

The Hawaiian governor issued an emergency order to de-fuel the Red Hill Facility. The US Navy has enlisted top lawyers to make sure its 600m liters of petroleum stay perched above our water supply

This [fuel facility] is not the eighth wonder of the world. It is Frankenstein’s monster. And we have to kill it before it kills us.”

This is the plea from Marti Townsend, one of more than … [more…]

Florida begins emergency feeding, rescue of starving manatees

Florida will begin emergency feeding and rescue of starving manatees

Record numbers of endangered manatees are dying as polluted waters kill off their food sources

Florida wildlife officials will undertake a manatee feeding and rescue operation involving hand-feeding the mammals romaine lettuce, amid unprecedented mortality among the gentle aquatic creatures affectionately known as “sea cows”.

Typically, manatees return to warm water winter feeding grounds, where they feast on plentiful seagrass.

But algal blooms from polluted waters have devastated seagrass beds, … [more…]

Opinion

Fresh, potable water is an everyday miracle in the middle of the Pacific Ocean. To have enough to supply millions with (relatively) few constraints on usage? It’s almost unimaginable. And, perhaps, too precarious to want to imagine.

Of course, the water in Hawai’i serves more than latecomer humans. Endemic land species of every kind, exotic imports, and unique hybrids do not spring from saltwater. … [more…]

Forest defoliator outbreaks alter nutrient cycling in northern waters

Forest defoliator outbreaks alter nutrient cycling in northern waters

Abstract

Insect defoliators alter biogeochemical cycles from land into receiving waters by consuming terrestrial biomass and releasing biolabile frass. Here, we related insect outbreaks to water chemistry across 12 boreal lake catchments over 32-years. We report, on average, 27% lower dissolved organic carbon (DOC) and 112% higher dissolved inorganic nitrogen (DIN) concentrations in lake waters when defoliators covered entire catchments and reduced leaf area. DOC reductions reached 32% when deciduous … [more…]

A series of recent research papers from a McGill-led team has found that the herbicide glyphosate—commonly sold under the label Roundup—can alter the structure of natural freshwater bacterial and zooplankton communities. Notably, the researchers found that … [more…]
