Current / recent research
Much of Ian Boomer's research focuses on a group of calcareous microfossils, the Ostracoda (or ostracods). An ostracod can be thought of as a microscopic shrimp-like organism (usually less than 1mm long) living inside a bi-valved carbonate shell or carapace. These little bugs have been around for the last 500 million years and live today in just about every aquatic environment. Their fossils can be used to date rocks, record major changes in the world’s oceans, trace climatic changes such as sea-level rise amongst other uses and even track pollution. They are still alive today (with thousands of living species known) and can be found swimming or crawling, often in great numbers, everywhere from garden ponds to coastal rock pools, rivers, lakes and oceans. One group has even learnt to survive out of water.
Ian Boomer has a particular interest in the geological record of ostracods around the period of the latest Triassic and Early Jurassic (about 200-174 million years ago during one of the ‘Big-Five’ Phanerozoic extinction events). Another part of his research focuses on using these fascinating little bugs to find out more about the rapid, global climatic changes that occurred between about 15,000 and 10,000 years ago. His studies concentrate on a region of the world that encompasses the great inland seas of SW Eurasia, the Aral, Caspian and Black seas.
He has also studied ostracods form the deep sea of the Pacific ocean investigating the evolution of those faunas that lived on the tops of underwater mountains (often extinct undersea volcanoes) and how those faunas evolved in isolation from the even deeper water environments of the surrounding sea floor.
Ian is also involved with a number of archaeological projects in the north east of the UK (Bamburgh Research Project, Howick Project, Low Hauxley, “Rescued from the Sea”) where he is involved in various aspects of geoarchaeology, landscape and sea-level change, sedimentary coring and description and analysis of biological remains.
Water quality and isotope studies
Ian Boomer is currently employed as a Research Fellow in GEES, University of Birmingham, as the Laboratory Manager for the Stable-Isotope Laboratory (SILLA) which he helped establish and was commissioned in December 2005.
The laboratory focuses on the stable-isotope analysis of hydrological, biological and geological samples from a wide range of projects, including cave systems, rivers, lakes, coastal sea-water and deep ocean settings.
