    Web Diagramming Rocks: Paper Named Among 10 Best

    The researchers found the diagramming helped students form “knowledge networks” that led them to a better understanding of the material.

    It takes a lot of instruments to collect ice measurements!

    The Operation IceBridge (OIB) mission is a truly collaborative project with several agencies and multiple instruments involved in collecting independent measurements. The data is then analyzed concurrently to develop an understanding of the ice processes underway. The measurement of sea ice is an excellent example of how multiple methods of measurement are needed to collect…

    Jakobshavn Glacier continues to provide surprises!

    We have moved south! One of the many challenges of our Greenland survey is the need to switch bases in the midst of the season since Thule Air Force Base also serves as a staging location for a major resupply mission for many of the Arctic outposts.  The whole set up has to be packed…

    Flying Over the Arctic, Collecting Data and Enjoying the View

    By Brian Moses This past week, Operation IceBridge undertook a detailed survey of the ICEX camp, situated on the ice sheet north of Alaska. This complex 3 day mission involves a transit to Fairbanks, AK over the top of the world, refueling in Fairbanks and flying the survey on day two, and a low-altitude nighttime…

    IceBridge Team Settles in the North

    Operation IceBridge has returned to the Arctic for a second Greenland season collecting critical measurements of Arctic sea ice cover and thickness and Greenland’s coastal outlet glaciers. Traveling on a DC8 outfitted as a cargo plane with only 6 rows of seats, the team flew from Baltimore MD to Thule in northern Greenland. The workhorse…

    Done in Khulna, back to Dhaka and then home

    On Saturday, we finished up work at the site.  Even at the last minute, it threw some challenges at us.  We began the day with out reduced group eating breakfast down the street.  We could no longer take the mediocre food at the hotel.  Dhiman and Babu had been eating there for days.  Besides paratha,…

    Finishing up in Khulna

    The last two days have been a little different as I spent much of them in Khulna rather than at the site. Since the Islam family does not have electricity, Hafizul would have to carry the expensive EDM (Electronic Distance Meter) and laptop back and forth to Khulna University to charge. However, we have an…

    Finally getting it right

    We are driving back to Khulna at 10:30 after our third excellent day in a row.  However, there were still a lot of hiccups along the way. Yesterday, we were set to install the deep well, but when we arrived they were just starting to pull the pipe from the deep well.  We had hoped…
