Humanity is affecting the ocean in profound ways. In this post, I will briefly explore two of those impacts from the perspective of a professional oceanographer. First, the effects of human use of fossils fuels leading to increased levels of atmospheric carbon dioxide and so to global (including ocean) warming; and second, human disposal of plastics in the ocean. The importance of the latter was highlighted by David Attenborough in the BBC’s “Blue Planet II” in the autumn of 2017, leading to an increased public awareness of this issue. However, both issues have been of concern to oceanographers for many years. Continue reading →
How do you imagine a coral reef? Have you had the privilege of seeing one through your own dive mask, or have you sat in the comfort of your living room watching beautifully shot images set to dramatic full orchestra soundtracks?
Healthy coral reefs are a festival of colour, shape, sound, and activity. They are full of interesting characters, each playing their part in the functioning of the ecosystem – from the sponge that filters out harmful viruses from the water column to Continue reading →
The mist wisped its way over the sea towards the shore, curling over the beach and on to the promenade. A deepening haze softened the contours of the beach huts and the cliffs behind. I walked more slowly, feeling my way ahead. The air was unusually still. Scanning the beach I glimpsed a shape there. It seemed to be blue and white; an abandoned deckchair perhaps? Coming closer I could see it was a figure stretched out in the sand. Probably one of those giant puppets from yesterday’s carnival. Then I heard a faint moan. I approached cautiously. As I drew closer I could see wide canvas trousers and a short jacket with brass buttons. A scene from my childhood floated past me. It was a wet day and I was asking when it would be dry enough to play outside. ‘Is there enough blue sky to make a pair of sailor’s trousers?’ my mother asked, looking up at the sky. So perhaps this figure was a sailor? He seemed rather small. There was seaweed hanging from his body. Had he nearly drowned and been washed ashore? I hesitated, being somewhat squeamish and also aware that I was on my way to a rehearsal. Continue reading →
“The oceans cover 71% of the Earth and our planet could equally well be called Ocean as opposed to Earth. Seen from space our planet is indeed a beautiful ‘blue marble’ spinning in the vastness of the cosmos and, as far as we know, the only place in the universe with intelligent beings who can contemplate and understand something of themselves and the creation in which they live.
The oceans may well be where life originated on our planet and they harbour life on all scales, from Continue reading →
It is easy to forget that we human beings are not the be all and end all of God’s magnificent creation. From one perspective we are simply creatures in it. From another perspective we are unique in his creation in being made in the image of God (Gen. 1:27). However, both the beauty and abundance of marine life and the biblical passages concerned with the sea show that Continue reading →
