Much like trees, clam shells have growth rings. The chemistry of these rings can be used as a proxy for ocean chemistry. Recently, an international team of scientists used the growth rings found in shells of Arctica islandica to produce an annual absolutely dated marine δ18O record for the last millennium which was published in …[Read More]
Coral reefs and other benthic marine ecosystems play a very important role in the biogeochemical cycles of our oceans. However, laboratory based study of these environments ranges from being difficult to actually impossible. In order to look at the microscopic-scale processes that occur in the benthic environment a team of scientists developed the Benthic Underwater …[Read More]
Meristems are groups of undifferentiated cells found in growth zones of plants. Active meristem zones have a different cellular organization than inactive zones, and up until recently no fossilized active root meristem had been found. A team of scientists recently found and described the fossilized remains of an actively growing root meristem dating from the …[Read More]
Honey bees, a highly important pollinator, have suffered a number of declines and population collapses in recent years. The growth of urban centers has contributed to a loss of foraging habitat and an introduction of new food sources. A recent study conducted across the rural-urban boundary of Raleigh, North Carolina, USA examined the feeding sources …[Read More]
Summer time as an early career geochemist can mean many things, to some it is vacation time, to others it is field season, and yet for others it is time to enroll in a summer school. ECORD, the European Consortium for Ocean Drilling, offers at least one summer school a year. If you work with …[Read More]
