Due to increases in the carbon dioxide (CO2) caused by global human development, Alaskan Fisheries are being threatened from ocean acidification. There are at least two highly productive crab fisheries located in state that could be harmed by the uptake of atmospheric CO2 into marine waters. A study published in Progress in Oceanography addresses this risk to our fisheries.
Ocean acidification is a term used to describe the decrease in pH and increase in carbonate ions caused by adsorption of CO2 gas being pumped into the air. This greenhouse gas is produced primarily through the burning of fossil fuels. Many marine organisms depend on the deposition of calcium to build their shells or bodies. These include crab, coral and shellfish. Acidic water interferes with the construction of these shells.
Red King crab and Tanner crab, economically important species in Alaska, are seen as especially vulnerable to effects of ocean acidification. Due to the cold waters of the state, they take longer to develop their shells and are in contact with the acidic water longer. Additionally, this cold water adsorbs more CO2 than waters found in lower latitudes and arctic currents force more acidic water towards the ocean’s surface. Read More
In this work from the U.S. Coast Guard Art Program 2014 Collection, “Medical Rescue in Juneau‚” a Coast Guard Air Station Sitka MH-60 Jayhawk helicopter crew prepares the victim of a nearly fatal fall for evacuation from St. James Bay to Juneau where he will be transferred to a nearby hospital for treatment. In an average year, the Coast Guard responds to 25,880 search and rescue cases and saves 4,880 lives. U.S. Coast Guard Art Program work by Peter DeWeerdt.
Survival manuals are commonly found in an outdoor enthusiast’s bookcase. Though many books possess useful information, most of the material is routinely reproduced from text to text. Reality television programming now focused on prepping for the end of the world has just fueled further demand for the genre. In these conditions, Tim MacWelch has written a book titled Prepare for Anything Survival Manual that even a jaded sourdough would find remarkable.
The topic of survival and preparedness enjoys a different perspective in the north. Rural residents have long known the value of preparedness and self-sufficiency. Poor weather, power outages and transportation delays are not uncommon. MacWelch offers advice in 338 different areas that are broken into three board categories: gear, skills and survival. Many of the topics discussed in the book would be of interest to even the most prepared.
Tim MacWelch operates his own survival school and has vetted the skills offered in this book. Tim was been instructing outdoor skills for 18 years, actively writes for Outdoor Life and is the chief contributor to the company’s survival skills website. MacWelch’s expertise leads itself to preparing for natural disasters, learning wilderness survival skills and acquiring knowledge to live off the grid.
