"Study Reveals Rapid Sinking of East Coast Cities Including New York and Washington"

A recent study published in PNAS Nexus reveals that critical infrastructure along the US East Coast is at risk due to land subsidence, with areas sinking by several millimeters annually, exacerbating the threat of sea-level rise. This subsidence, caused by factors such as sediment settling and groundwater extraction, affects millions of people and properties, with infrastructure like levees, roads, and railways also at risk. Differential subsidence, where different areas sink at varying rates, poses a particular threat to the structural integrity of buildings and infrastructure. The study emphasizes the urgent need for detailed data and improved groundwater management to mitigate the risks and costs associated with subsidence.

"Global Study Exposes Vast Number of Unmonitored 'Dark Vessels' Threatening Oceans"

A new study using satellite data and deep-learning models has revealed a significant number of "dark vessels" in the world's oceans that are not publicly tracked, including 72-76% of fishing vessels and 25% of transport and energy vessels. This lack of tracking creates blind spots in our understanding of maritime activity, which is crucial for managing resources and protecting marine ecosystems. The study, aiming to increase transparency and aid in ocean management, has been published in Nature and provides detailed maps of industrial activity at sea, highlighting the need for better monitoring to address issues like illegal fishing and the protection of marine species.

"Alaska Cancels Snow Crab Season Again Amid Continuing Population Decline"

Alaska's snow crab season has been canceled for the second consecutive year due to a dramatic decline in the crab population, with an estimated 90% drop. This has caused significant economic strain on the local fishing community. The decline is attributed to environmental changes and a marine heat wave that affected the crabs' food supply, leading to starvation. Biologists and the Alaska Department of Fish and Game hope that suspending the fishing season will allow the crab population to recover. However, there is growing concern that the effects of climate change may continue to negatively impact the species and the fishing industry that relies on it.

"AI and Satellite Data Uncover the Hidden Congestion of 'Dark Vessels' in Global Seas"

A study by Global Fishing Watch, supported by Google, has revealed that a significant portion of the world's industrial fishing vessels, as well as transport and energy vessels, are not being tracked publicly. Using AI to analyze satellite data, researchers found that 72 to 76 percent of fishing vessels and nearly a third of other vessel activities are "dark," meaning they are not visible to public tracking systems. This research, which also noted a substantial increase in offshore wind turbine installations, aims to provide policymakers with comprehensive data to address maritime activity's impact on the climate crisis.

"Satellite Data Uncovers the Vast, Unseen Industrialization of Our Oceans"

Researchers have utilized satellite imagery and deep learning to create a detailed global map of industrial activities at sea, revealing extensive fishing and non-fishing vessel activity that is not publicly tracked. This study, analyzing 2 petabytes of satellite data from 2017-2021, found that about 75% of global industrial fishing and 25% of other vessel activities evade public monitoring systems. The findings highlight the significant environmental impact of the 'blue economy' and the need for better oversight to ensure sustainable use of ocean resources. The data also show a decrease in fishing activity during the COVID-19 pandemic, contrasting with the stability or growth of transport and energy-related vessel traffic. The study underscores the importance of accurate mapping for managing human activities in the ocean and informs policies on reducing greenhouse gas emissions from maritime industries.
