Blue Fiord reefs - Panoramic aerial view of a Middle Devonian reef exposed on Princess Royal island between Banks and Victoria islands, Canadian arctic (latitude 75 degrees N). This reef is part of an ongoing PARRC reef research project underway since 2000 by Dr Paul Copper and Dr Evan Edinger (now in Newfoundland, Memorial U.) to study a large, 2500 km long coral-sponge reef tract which grew in the Canadian arctic about 387 million years ago, when this area was in the tropics.
Chicotte reefs - These coral-sponge reefs, exposed today on tidal flats in the Gulf of St Lawrence, Anticosti Island, are part of the very long research program of PARRC. These reefs are up to about 800m in diameter, and outcrop along a distance of ca, 70 km along the coast and inland. This helicopter view shows what you see from above.

Global mass extinctions

One of the popular themes which has captivated world media attention in the last decade of the 20th century, centers around the question of what happens to life when a large meteorite or bolide from outer space, say one with a diameter of 20 kilometers or more, collides with Planet Earth. Some may have seen this through the dramatic eyes of Hollywood, for example, the films "Armageddon" and "Deep Impact", which focus on the human response to such a catastrophe.

We have a fairly good idea what will probably happen physically by carrying out impact experiments at a small scale, and by modeling such events on a planetary scale. Scientists have also studied, of course, large impact craters on earth (such as the Sudbury basin and lake Wanapitei), and those on the moon, Mars, Venus and other planets and their moons: these give us a rough idea of the shapes and sizes of craters, and the "on ground" effects on the rocks which they strike. We also know how frequently such events occur. According to Dr Richard Grieve (Ottawa, Geological Survey of Canada), one of the world's impact experts, large chunks of 10km or larger strike Earth approximately every million years on average. This calculation is based on the age dating of known craters, especially those of the last half billion years of earth history. But is there a pattern to these impacts? The experts are divided: some suggested 15 years ago that these may strike more commonly in cycles of 30 million years as the earth passes through the Oort Cloud, a cluster of large chunks of rock past which the Solar system circles. Others see no such pattern, and today this idea is generally discarded.

However, life on earth should also record the severity of impacts: such catastrophes, at such scales, should have a major effect on life, by extinguishing vulnerable species of plants and animals, or large groups, and wiping out whole ecosystems. Large scale elimination of species, usually 50% or more of the planetary community, is called global mass extinction. Symposium SY 5, is a special get together of scientists who will be discussing this controversial aspect: is there any correlation between known global mass extinctions and ET impacts? Do the five major mass extinctions in the past half billion years, show a pattern in common with impacts from outer space? Large impacts should create instant extinctions.

We now have also clear evidence of a very large impact crater, about 150km across, at the Chicxulub site in the Yucatan, Mexico: this crater, buried under several hundred meters of limestone today, coincides with the K/T boundary global mass extinction (from Cretaceous / Tertiary, 65 million years ago), during which a number of dinosaurs disappeared on land, and exotic molluscs like clams and squid relatives vanished in the oceans. The K/T boundary event is matched by evidence for large tsunami splash waves, chemical signatures in the oceans, and shocked impact glasses: its presence is not disputed. However, puzzling questions remain as to whether the impact had a major effect on life, since many species survived. Many scientists who study the detailed record of species below the impact boundary are suggesting that the end Cretaceous, the last 3 million years of it, had already seen a massive loss of many dinosaur species, and the loss of complex systems such as tropical reefs before the meteorite struck. The nature of the survivors themselves will also give us clues as to how severe these extinctions were and how selective.

The global carbon cycle through the last half billion years

The single largest reservoir for the storage of carbon on planet earth is crustal carbonate rock, i.e. CaCO3 or limestones. It far exceeds the reservoir we see in coal, oil and gas, and other carbon matter stored in the crust. Carbon is the most essential element to life, in addition to water, but it is in relatively short supply compared to elements like iron, magnesium and sodium. The largest surface reservoirs on earth are organic matter, for example, plants, and the carbon dioxide (CO2) in the atmosphere, through which carbon is cycled. The ultimate source for most carbon is via volcanic gases, through erosion of soluble minerals on the earth's surface, and through heating of rock via metamorphism.

One question is, what is the role of limestones in the long term, and are there evident cycles during which limestone was more rapidly deposited or eroded than others? We know that the acme or peak of CaCO3 production is via the secretion of skeletons by animals and plants, e.g. corals and algae, in the warm oceans, most importantly, in reefs. Such major trends are strongly influenced by global climate change, and are strongly affected at times of global perturbations in the earth-atmosphere system, such as during global environmental stress and mass extinction. I study such patterns by plotting global trends in microbial, algal, coral and sponge reef distributions, e.g. thickness and diameters of reefs and their components. These are then placed into paleogeographic maps that show where the ancient oceans and land areas were located, and these are then analysed over particular time slices of 1 million years. More than 12 major cycles have already been plotted on a worldwide basis. This data is collected in the field and culled from the literature, and contacts with colleagues around the world. To confirm major paleoclimate trends we take stable isotope samples from fossil CaCO3 skeletons, especially brachiopods, which are particularly sensitive, and which tell us the ambient temperatures of shallow surface seawaters. Thus we have a good overall view of the world's oceans in both space and time, and a reasonably reliable set of indicators for global climate change. This has told us that the earth was much warmer in the Middle Paleozoic than today, that is, about 25-30 degrees celsius global average temperature, versus today's global averages for surface seawater and sealevel atmosphere, of about 15C. Thus today, in recent human history, global average temperatures are not nearly so warm as they were then, even with modern trends of atmospheric warming due to the greenhouse effect of CO2 gases.
