I have loaded into Alfresco a location map of the summit of Axial Volcano with our preliminary buoy, geo nodes, and hydro node sites connected by cable runs that take into consideration seafloor terrain. Cable route distances are indicated. The MASE buoy is a little south of where the NeMO buoy used to be, but still is as far away from the NeMO instrument sites as it used to be. Geo node 1 is located at a NeMO benchmark and BPR site, and the Hydro node at their RAS site. Several of the geo nodes are outside the caldera in regions we hope to map with the AUV this summer, but are covered by EM300 data. Positions of the preliminary node locations are as follows:

Node             Latitude        Longitude      Depth

MASE buoy   45.938007   -130.007121    -1547.8

Geo node 1    45.9552       -130.01005     -1536.9

Geo node 2    45.950912   -129.971544    -1525.5

Geo node 3    45.914742   -129.962502    -1580.0

Geo node 4    45.911048   -130.00589      -1555.3

Hydro node    45.933167   -129.982285    -1522.1

From Mark C. 7/16/2008: Here is an additional map from Bill Chadwick showing 1.25km buffer around currently visited Axial sites: nemo_mbari.jpg 

From Jenny P. 7/17/2008: A new map is in the Alfresco site, which shows 1162m watch circles (recalculated by Mark yesterday based on a better depth estimate: "The correct watch circle radius for a 1.25 scope and 1550 meter depth is 1162 meters.")  AxialObservatoryMap_prelim2.jpg
