Geotimes July 2006 Kathryn Hansen	Ship Logs Record Earth's Magnetism New information gleaned from old ships' logs is now leading to a better understanding of the magnetic field's past strength, which is turning out to be more erratic than some scientists previously thought.
Geotimes July 2006 Carolyn Gramling	Sri Lankan Water Post-Tsunami According to a new study, tens of thousands of wells in Sri Lanka's coastal areas are still contaminated with seawater and are unusable, despite last winter's heavy monsoon rains -- and it may be several more monsoon seasons before the coastal aquifer can supply potable water again.
Geotimes July 2006 Carolyn Gramling	Afar From Close-up Powerful stresses in the crust lead to frequent earthquakes and volcanism in the Afar Depression of northeastern Ethiopia. Researchers now say that the source of this activity reveals a possible new connection in Earth's interior.
Geotimes July 2006 Kathryn Hansen	Dunes on Titan Sand dunes discovered on Saturn's moon Titan are structurally similar to dunes in Earth's Namib desert in southern Africa. The dunes' various orientations are helping astronomers map Titan's wind patterns.
Geotimes July 2006 Carolyn Gramling	Earth Soaks up Seawater Geologists have long thought that seawater does not travel very far through Earth's interior A new geochemical study, however, is challenging that notion, saying that traces of seawater exist deep inside the planet.
Geotimes July 2006 Megan Sever	Climate Resolution A resolution on global warming, stating that the House of Representatives recognizes that warming is real and caused by excessive greenhouse gases in the atmosphere, reached the floor of the House, but was blocked from a vote.
Geotimes July 2006 Rasoul Sorkhabi	Energy Problems Need Energy Solutions A sensible energy policy should plan to heal, not worsen, our country's addiction to oil. This can be achieved by reducing our oil consumption, and diversifying our energy sources to create an "energy-mix" market. Both strategies are necessary.
Geotimes July 2006 Naomi Lubick	H. Jay Zwally: Glaciologist by Chance Zwally does most of his fieldwork in Greenland, but the groundbreaking glaciologist has also gone to Mount Kilimanjaro to field check satellite data measuring ice around the planet. His most recent publication has kicked up a little controversy.
Geotimes June 2006 John Rowland	Coastal Maryland: On the Lookout for Ghosts, Fish and Fossils Point Lookout, Md., has beautiful coastlines along the Chesapeake Bay, where recreational opportunities abound, including boating and fishing. The region has a rich geologic and cultural history.
Chemistry World June 23, 2006 Jon Evans	Phosphorus Concentrations Catalogued in Coral A species of cold-water coral keeps an accurate record of marine phosphorus concentrations, report geoscientists. The coral Desmophyllum dianthus incorporates phosphorus into its skeleton at concentrations proportional to those in the surrounding ocean.
