How are melting ice sheets affecting seawater salinity levels?

By : Craig Harrison |October 06, 2016 |Blog |0 Comment

Each year, findings and studies are published which promote the fact that the world is changing at an alarming rate. The world’s oceans are no exception. A new study published in Nature addresses one of the biggest uncertainties in global warming’s effects on the ocean, specifically relating to the ocean’s salinity and the shifting of the polar ice caps.

The impact of the oceans heating up

By : Craig Harrison |September 20, 2016 |Blog |0 Comment

Following the hottest July and August on record, the earth’s rising temperature is having a number of knock on effects on rising ocean water temperatures around the world. A new study by The International Union for the Conservation of Nature has described rising ocean temperatures as “the greatest hidden challenge of our generation,” and outlined findings that indicate that oceans absorb up to 90% of the extra heat that our greenhouse gases trap. This study paints an alarming picture of oceanic conditions and the future of our planet.

Are agricultural chemicals affecting our water?

By : Craig Harrison |September 07, 2016 |Blog |0 Comment

With the rate at which modern towns and cities expand it’s inevitable that the volume of separation between agricultural facilities and highly populated areas is shrinking. The loss of these areas can have a lasting impact, particularly when it comes to our water supplies.

From an increase in water treatment prices to potentially dangerous levels of nitrogen, agricultural facilities encroaching on water supplies has the potential to cause lasting, and potentially harmful, damage.

How levels of acidity can affect aquatic ecosystems

By : Craig Harrison |August 24, 2016 |Blog |0 Comment

We already know that the pH of water can have detrimental effect on human health, and can be affected by a number of different factors including: residue from volcanic vents, acid rain and global warming. But just how big of an effect can it have on delicate aquatic ecosystems? A number of recent stories and headlines have indicated that the answer is, quite a lot. From fishing practices in Alaska, to dampened escape responses in black turban snails, acidic water is showing increasingly observable pressure on aquatic habitats.

Brexit and the environment

By : Craig Harrison |August 10, 2016 |Blog |0 Comment

The EU results have caused a massive stir in the political and economic landscape with many people still debating the ramifications. Perhaps less documented however is potential effect that leaving the EU could have on the environment and legislation to protect it. Though debating the positives of the EU may seem somewhat redundant now, there was little denying that in most cases, their environmental policies, though stringent at times, helped to maintain a level of conformity across the continent.

Dissolved oxygen’s effect on ecosystems

By : Craig Harrison |August 10, 2016 |Blog |0 Comment

Dissolved oxygen (DO) is a measure of the amount of oxygen dissolved in water. It can be caused by a process of aeration of water flowing through rapids or falls, a byproduct of photosynthesis and the atmosphere. Monitoring DO levels in water may be more important than you think. From dead fish washing up on the shores of Singapore, to historically low levels of brown shrimp, DO is having an adverse effect on ecosystems all over the world. (more…)
