Propane’s Economic Edge for Ports During Trade Uncertainty

costs in port operations is fuel. Diesel and gasoline prices can be heavily impacted by the global oil market, which can be affected by several factors like international conflicts, policy changes, tariffs, and more. Propane, on the other hand, is predominantly produced domestically here in the United States, so it benefits from a more stable supply chain and fewer price fluctuations. Compared to diesel and gasoline, propane helps protect ports from sharp price spikes that can quickly consume their annual fuel budget for the year. Propane suppliers can also offer port operators mutually beneficial

Seismometers Retrieved for Slow-Slip Earthquake Study

“dives” or subducts beneath another. These dangerous fault lines produce the world’s largest earthquakes and tsunamis, such as the 8.8 magnitude earthquake offshore Kamchatka earlier this year.Beginning in late 2022, an international group of scientists from New Zealand, Japan, the United States, and Germany deployed a dense network of seafloor instruments offshore Gisborne to monitor both fast (seismic) and slow motion (lasting weeks to months) fault activity.The instruments that have been retrieved over the last two weeks will enable detailed understanding of slow-slip events, a type

Overfishing Deal Reached After 20 Years of Negotiation

from the Pew Charitable Trusts said.Governments around the world pay out roughly $35.4 billion annually to their fishing fleets, including fuel handouts that allow them to fish in distant oceans, a 2019 study in Marine Policy showed. It listed the top five subsidisers as China, the EU, the United States, South Korea and Japan - though not all of them are within the scope of the WTO deal.Negotiations on further fishing rules covering divisive issues excluded from the first deal have floundered, as India and other developing economies seek carve-outs that many other states see as unworkable.The
