Exploring arctic plants and lichens: An important conservation baseline for Nunavut's newest and largest territorial park      (via sciencedaily.com)     Original source 

A comprehensive study of the floristic diversity of Agguttinni Territorial Park, Nunavut's newest and largest Territorial Park, has documented 141 vascular plant, 69 bryophyte, and 93 lichen species from this unique protected area on northern Baffin Island. Through a combination of extensive fieldwork in 2021 and examination of hundreds of existing herbarium specimens, the authors have documented species newly reported for Baffin Island and have crafted a biodiversity baseline important for park management and conservation.

New study quantifies health impacts from oil and gas flaring in U.S.      (via sciencedaily.com)     Original source 

A new study finds that pollution from oil and gas venting and flaring results in $7.4 billion in health damages, more than 700 premature deaths, and 73,000 asthma exacerbations among children annually. Researchers also conclude that emissions are underreported and controlling emissions is not only profitable for operators, but also can significantly improve public health in surrounding communities.

History repeats as Coral Bay faces mass loss of coral and fish life      (via sciencedaily.com)     Original source 

A perfect storm of environmental factors has seen a monumental loss of fish and coral life at a popular area of Ningaloo Reef in Western Australia's Gascoyne region -- however research into the event shows there is hope it will recover. In March 2022, during the annual coral spawning event, calm weather and limited tidal movement combined to trap the coral's eggs within Bills Bay, at the town of Coral Bay. This led to an excess of nutrients in the water which consumed more oxygen than usual -- causing massive numbers of fish and corals to die from asphyxiation.

AI making waves in marine data collection      (via sciencedaily.com)     Original source 

Numerous measurement stations around the world provide us with data about air quality, allowing us to enhance it. Although we are increasingly collecting data from marine areas, access to such data is considerably more challenging. Signals are poorly transmitted through water, differences in both pressure and currents hinder measurement devices and there is an absence of pre-constructed computing infrastructure. Could intelligent technologies help us improve marine data collection?
