Fish Counter

July 2, 2007

Today Michael dove down and retrieved a fish counter that was installed below Forerunner. This equiptment was a Vr2 distributed by VEMCO. Now we are sending it back to Mary Moser with NOAA Fisheries.

Woody Island Cleaning

[img_assist|nid=554|title=Woody Island Tower|desc=|link=popup|align=left|width=100|height=75]

June 27, 2007

Today we went up to the station at Woody Island. The solar pannel reading had nearly flat lined because of the cormorant colony that nests on it. We put in at John Day and began heading up. Along the way we stopped at sveni (Svenson Island) and marsh (Marsh Island). We then reached woody (Woody Island) and Michael climbed up and cleaned off the solar pannel. Once done we headed over to eliot (Elliot Point) and mottb (Mott Basin).

Corie Excursion

Week 2

Week 2:
This week on Monday I finished adding cruise sample water to the rest of my plates, as well as a couple of additional ones Suzanna had handy. We also checked out the plates I had done on Friday. Not many colonies growing yet. In addition, I inoculated my liquid media with sample water using 48 well plates. Now the waiting begins. We will get all kinds of colonies growing on our plates, but we only want the manganese oxidizers. These microbes form light brown colonies and can take a few weeks to form. If we do get the colonies we want, we’ll streak them out and try to cultivate them individually.

The Search for the Manganese Oxidizers

Week 1:
Hey Everybody,
I am doing a 10 week internship this summer, at The Center for Coastal Margin Observation and Prediction (CMOP), located at OHSU's Department of Science & Engineering in Beaverton Oregon.

CMOP’s mission statement is: “to improve significantly our scientific understanding of the river-to-ocean environment characterized by highly complex interactions among watersheds, estuaries and the ocean's continental shelf.”

Hypoxia and Estuarine Turbidity Maxima

June 25, 2007

Hi, my name is Christina Tweed and it's my first day here at M.E.R.T.S. I just graduated from Astoria High School and am planning on going to Oregon State University in the fall.

Today I researched hypoxia and estuarine turbidity maxima in anticipation of CTD sets.

The first step was researching what these were as well as the history that goes along with them. After looking these up I studied the protocol for the research that went along with these terms. This gave me a better understanding of some of the reasons why we are doing these CTD sets.

Last Week

This is the last week of my project. I spent considerable time trying to get my program to work with Joseph Zhang’s larval tracker. However, I have had many setbacks with this process. I couldn’t compile the files I got from Joseph and using UNIX is still not easy for me. However, Bill Howe and Ethan VanMatre helped me get the multiple links file working. But, the particle tracker is still missing files.

CTD Cast - Forerunner June 5, 2007

Sped up, elapsed time is approximately 6 minutes.


This week I spent some time going over the variables and deciding which ones were related to corie data and which ones can interact with the particle tracker program. I met with Joseph Zhang and discussed appropriate input for the program. In addition, I spent considerable time developing a framework with a functional input/output. I used random numbers to simulate ocean forcings and larval behavior. The output was a list of x,y,z coordinates at each arbitrary time step. I accomplished my goal of getting a working piece of code, upon which, I plan to develop the larval tracker.

Status of hindcast runs - May-2007

As of May 29:

db11 - 2006 complete through week 26, setups for the remainder of 2006 are complete and are in the queue to run
db14 - 2-3 weeks of the first 2 series of 2006 need to complete
db16 - done through 2005, waiting on db14 to complete for 2006
