Summary of Field Work: |
Jumbo piston coring cruisel departing from and returning to Fremantle Australia . Our cruise plan (detailed in budget explanation) includes 10 days total for multibeam and 3.5 kHz surveying at each of the 4 designated coring areas. |
|
Summary of Facility Requirements: |
We request the Oregon State University seagoing coring team to support the coring effort. We require jumbo piston core capability, trigger cores and a multicorer. We require multibeam and 3.5 Khz seismics for surveying potential coring sites. We will also need CTD and a Niskin bottle rosette for water column sampling. |

Optimum Start Date:

Dates to Avoid: |
We need to have cruise dates squarely in the Austral summer -- Experience has taught us that late Feb leading into March is too late to expect good weather this far south. Likewise Anytime before mid November is also marginal weather-wise.
We have obtained the avg monthly winds (2001- 2010) for this region of the Indian O. Avg in Nov is 11m/sec, Dec = 10m/sec, Jan=11m/sec, Feb= 11.5, Mar=12. The maximum average winds are:
Nov 12.5m/sec, Dec= 11, Jan= 12.5, Feb=12, Mar=13.

For a point in the SE Indian Ocean at 55S, 85E, the graph shows the individual monthly means for each year in 2000-2010 (blue squares) and the means by month (red diamonds, orange line) plus/minus one standard deviation (orange error bars).
Data plotted here are from the Cross-Calibrated, Multi-Platform (CCMP) Ocean Surface Wind Velocity Product for Meteorological and Oceanographic Applications computed at NASA GSFC from satellite based wind speed observations in 2000-2010. [NASA JPL Dataset ID: jplCcmp35aWindMonthly].

Description of Repeating cruise requirements: |
none |
Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations: |
Coring in the Southern Ocean requires reasonably calm conditions. Conditions in spring and fall can be brutal and winter is out of the question (Been there and didn't get to do it). The best window for this is Dec-Jan- early Feb. We do not expect funding before 2016 so request this cruise for late Nov - mid Dec 2016 or earliest Jan 2017. |
