Liquefaction: a dangeous twist of physics that makes some cargoes dangerous

Jul 12, 2021

Today we’ll talk about liquefaction: the tendency of some cargoes that are solid (certain kinds of mineral ores), but can behave like liquids in a cargo hold under certain conditions. It’s a dangeous consequence of basic physics and how cargoes are loaded and stored. If that happens, it’s not a ship you want to be on.

Update on river cruises: what passengers should expect

Jul 06, 2021

As river cruises nationwide open up again, there are some caveats passengers will have to follow. The most important rule of thumb is that rules are different in different states and you need to be ready to adapt if you go.

A bit about that Heat Dome and how it relates to the Pacific Ocean

Jun 29, 2021

What’s wth this “heat dome” situation we’ve been experiencing in the Pacific Northwest, in areas that are normally cool? We’ll talk today about what causes a heat dome to occur. Part of it has to do with ocean temperatures in the Pacific.

Another cruise ship will be stored in Astoria

Jun 22, 2021

The Port of Astoria has made arrangements to store another ocean-going cruise ship at the port docks. She’s a U.S flag cruise ships called the “American Pride” and she is normally based in Hawaii where she takes passengers between island ports there.

Today marks the Summer Solstice in the Northern Hemisphere

Jun 21, 2021

Today is one of two annual astronomical solstice events. This one we call the beginning of summer in the Northern Hemisphere, and the start of winter in the Southern Hemisphere.

We’ll talk about what’s happening out there in space that so deeply affects us here on Earth.
