Wildlife

Massive Seaweed Bloom

For eight years, thick mats of seaweed have smothered coral reefs, trapped sea turtles and brought economic instability to coastal communities as reddish-brown gobs of foul-smelling sargassum wash onto beaches along the Caribbean Sea, Gulf of Mexico and tropical Atlantic.

These phenomena are symptoms of a massive seaweed bloom scientists are calling the Great Atlantic Sargassum Belt. Stretching up to 5,500 miles (8,850 kilometers) from the Gulf of Mexico to just off the coast of western Africa, the Great Atlantic Sargassum Belt appears to be the product of natural and human-caused factors.

The bloom began around 2009 when discharge from the Amazon River brought unusually high levels of nutrients into the Atlantic Ocean. Upwelling of nutrient-rich water off the west coast of Africa in the winter of 2010 further enriched surface waters with deep-sea nutrients; that upwelling also lowered temperatures of that surface water, allowing sargassum to thrive in the summer of 2011.

A similar combination of factors led to especially large blooms in 2014, 2015 and 2017. The largest recorded bloom occurred in 2018, when the Great Atlantic Sargassum Belt grew to a mass of more than 20 million metric tons. The high levels of nutrients from the Amazon River come from deforestation and fertilizer use in the Amazon basin.

Under normal circumstances, sargassum provides critical habitat for marine life. The seaweed oases attract fish, birds and sea turtles as well. Dolphins and sea turtles also benefit from the tiny patches of life floating in the open ocean, but thick mats of sargassum pose big problems for some wildlife and coastal communities. Sea turtles sometimes can’t swim through the dense mats to return to open water after laying their eggs.

Disease

White-nose Syndrome – California, USA

The fungus that causes White-nose Syndrome (WNS), a deadly disease of bats, has been detected in low levels in California for the first time. Fungal DNA of Pseudogymnoascus destructans (Pd) was detected in samples collected this spring from bats on private land in the Plumas County town of Chester.

Hepatitis A – Costa Rica

The Costa Rica Ministry of Health reports the outbreak of Hepatitis A (HAV) in the canton of Alajuela continues. As of June 28, there are 140 cases of HAV laboratory confirmed this year, 43 in June.

African Swine Fever

China – China’s agriculture ministry said on Friday it had confirmed an African swine fever outbreak in Luchuan county in the southwestern region of Guangxi that killed nine pigs on a farm. China has reported 143 outbreaks of the incurable disease since August last year, and culled almost 1.2 million pigs. Many outbreaks are not reported, farmers have told Reuters, and as many as half of China’s breeding pigs may have died or been slaughtered because of the spreading disease.

Bulgaria – Bulgarian Food Safety Agency (BFSA) on Friday evening confirmed a second outbreak of African swine fever in domestic pigs in three days, and the third since last August. The disease was located in a backyard pig farm in the village of Novachene near Danube River, only 16 km southeast of the village of Zhernov where the previous case was confirmed on Wednesday.

Poliovirus – Pakistan, Angola

Five additional wild poliovirus type 1 (WPV1) cases have been confirmed in Pakistan this past week, according to the Global Polio Eradication Initiative. Two cases were reported from Torghar district, two from Bannu district, and one from North Waziristan in Khyber Pakhtunkhwa province. Year-to-date, Pakistan has recorded 32 WPV1 cases.

Meanwhile Angola reported their second cVDPV2 outbreak this year. This one was in Kuvango district, Huila province.
