Silence from Scar Inlet and Cape Disappointment

September 8, 2012

NSIDC researcher Terry Haran returns to Scar Inlet and Cape Disappointment this fall to figure out why two AMIGOS units have been silent.

I return to Scar Inlet and Cape Disappointment in a month.

We haven’t received any communication from AMIGOS-2/4 at Scar Inlet since January 9, and AMIGOS-6 at Cape Disappointment has been silent since June 6. We think the AMIGOS-2/4 battery box may have shorted out due to the incursion of melt water. As for AMIGOS-6, that may have had its tower blown over or incurred some other kind of damage during a 60-knot wind event prior to its last communication. The UNAVCO continuous GPS units appear to be working but are in need of a communications upgrade, and the ones at Flask and Leppard glaciers may need their solar panels raised.

I’ve been busy preparing for the trip. I shipped AMIGOS replacement parts to Ronald Ross in Australia. Did the usual paper work for travel, began the physical qualification process required by the National Science Foundation-U.S. Antarctic Program, and collected a shipment of mechanical parts to be sent to Punta Arenas, Chile via Port Hueneme, California.

We’re not planning on visiting AMIGOS-3 since it continues to work well. It could probably use its solar panels raised, since the snow is just now touching the bottom panel. But that’s something we’ll leave for Ted during the upcoming Araon cruise with our Korean collaborators next year.
