Ever heard a tech diver talking about gradient factors? What are they and why are they so important?
Do you have enough breathing gas to complete your next dive?
Current increases in anthropogenic carbon dioxide emissions and related ocean acidification trends have parallels in an event 55 million years ago.
What does it take to make my actions and reactions second nature? These are questions that although not asked out loud are at the back of many of a diver’s mind, especially when embarking on a new skill, such as technical diving.
The Census of Marine Life was the largest survey of our oceans to date, involving an international effort to catalogue all known marine life over 10 years: around 6,000 new species were identified, equivalent to about one and half for every day of the program.
It’s 2015 and we still can’t talk underwater (well, we can, but at thousands of dollars per person, it’s too expensive for most recreational divers). Why is this and what is the future of underwater communication systems?
The ocean is the worlds largest ecosystem. Human influences are fundamentally changing the oceans which many countries rely on for economic revenue and food. The process of ocean acidification and global warming have the potential to decimate the ocean ecosystem, giving little time to adapt.
Researchers from Marine Scotland have uncovered unusual bacteria, coral and anemones on the seabed. The unusual ecosystem is thought to have occurred because of a process of ‘cold seap’ where gas from deep in the earth, leaks onto the seabed creating an environment capable of supporting rare species
An ancient plant that grew underwater, located in what is now known as modern day Europe, may have been the worlds first known flowering plant.
The floor of the Antarctic ocean is brimming with life. Some of these micro organisms, phytoplankton and bryozoans may be working together to act as a carbon sink slowing climate change.
