Endangered purple Cauliflower Coral pushed closer to brink of extinction after recent flooding

A cluster of Cauliflower Coral (Dendronephthya australis) credit David Harasti.
The gardens of purple, cauliflower-like corals that have long-delighted divers in Port Stephens waters are in significant decline, a Southern Cross University study has found.
Sand movement (sediment mobilisation) along with boat anchoring and moorings are the likely causes. Recent flooding has exacerbated the destruction of this soft coral which was recently listed as Endangered.
The study found the Port Stephens’ clusters of Dendronephthya australis, mapped by the research team in 2019, had declined by almost 70% in just eight years.
More recently, researchers were shocked to find high levels of run-off in the Karuah River catchment during the March 2021 floods has caused even further devastation of this population. Port Stephens, north of Newcastle, is the only known location where this species is found in large, habitat-forming clusters (aggregations). ....

Sentinel-2 Satellite-derived Bathymetry in Optically Complex Waters

Dublin Bay Case Study
May 12, 2021
Coastal areas are highly dynamic environments that are subject to diverse pressures, both anthropogenic (e.g. urban development, fishing, habitat modification) and natural (e.g. storms, erosion, floods). These pressures result in intensive and frequent seafloor alterations that demand efficient monitoring methodologies for repetitive updating of the seafloor morphology and bathymetry. Bathymetric information is essential in many coastal aspects, including environmental, management, research and economic.
Optical satellite data provides an efficient alternative to bathymetric derivation in shallow coastal waters ( ....

While Some Sharks Flee, Tiger Sharks Brave Stormy Seas

NEIL HAMMERSCHLAG
Sharks aren’t flying through tornados, but it appears some of them are weathering tropical hurricanes. Thanks to the surprise arrival of two tempests during two separate shark monitoring projects in 2016 and 2017, researchers were able to track four large shark species before, during, and after the storms. In a study that appeared online April 22 in
Estuarine, Coastal and Shelf Science, researchers reported that while other species retreated from the hurricanes, tiger sharks held fast.
The team took advantage of an opportunity to monitor something that hadn’t been tracked before, says Marcus Drymon, a marine scientist from Mississippi State University who was not involved in the work, but has collaborated with two of the study’s authors in the past. “It’s a really interesting study.” ....

When It Comes To Powerful Hurricanes, Not All Sharks Are Built The Same

A University of Miami study published this month found that while other sharks flee hurricanes, tiger sharks stayed put when Hurricane Matthew pounded the Bahamas in 2016. ....
