Computer Labs & Field Trips
The LAB Section of 260 is intended to acquaint you with the "details" of Puget Sound
- where the rivers are, how water moves in them as function of the landscape and end
up in the Sound, then how the Sound works. The Lab has two types of activities:
* Computer labs, where the principles of GIS and computer modeling are used to
"explore" the Sound. The Lab sessions will be held in SAL computer room, OSB 111.
After the first session, the Lab will be divided into 2-2 hour time blocks, with students
choosing either the 12:30-2:30 or 2:30-4:30 slot (to get more individual time on the
computers.
* Field trips, to "see" what we are talking about in the classroom and on the
computer.
Lab Assignment turn-in/grading:
In an effort to reduce paper waste, computer lab assignments will be
downloaded from the course website. Fill in answers on the provided
Word document worksheet, then save a copy on the SAL computers
(under c://students/OCN260/your_name). Email the completed
worksheet to Nick (prismta2@u.washington.edu). Grades will be posted
to the Section B course website by student ID #, and the worksheet will
be emailed back to you with comments.
THE LABS “knowledge, tools, and thinking”
10/6
Lab 1. (SAL) Arc IMS and the Puget Sound watershed
For our opening lab, we will do a “virtual” exploration of Puget Sound, learning
about what “attributes” are where. And begin to become familiar with “spatial
analysis” thinking and tools.
10/13 B Lab 2 (FT 1). Pipers Creek
We will visit Piper’s creek in Carkeek Park (northwest Seattle). The purpose of this
field trip is to look at a real watershed and see first-hand the challenges involved in
mapping the properties of a landscape over a wide area.
10/20 B Lab 3 (FT 2). Puget Sound Cruise, R/V Thomas G. Thompson
(overnight!)
We will take the unique opportunity to get to know Puget Sound up close and personal,
from the decks of the Thompson. We will leave at the normal time of 12:30 on
Tuesday, and return to downtown at 0600 on Wed. You will be part of collecting reallife “science” data.
10/27 B Lab 4 (SAL/OOB). Puget Sound “physical” models
We will look at two physical Puget Sound models, built here at the University of
Washington. These models simulate water circulation in various categories of estuaries
and the circulation of water through the Puget Sound Basin.
11/3 B
Lab 5 (SAL). iVPS
Today in lab we will utilize the Virtual Puget Sound (VPS) interface, a program
developed here at the University of Washington that allows the user to visualize the
circulation of water through the Puget Sound Basin.
11/10 B Lab 6 (FT 3). Cedar River
The purpose of this field trip is to examine efforts to manage a river with multiple
conflicting uses. The Cedar River is the source for approximately half of the
drinking water supply for the City of Seattle.
11/17 B Lab 7 (SAL). Duwamish/Cedar/ Black ArcIMS
The purpose of this lab is to use the Arc IMS Internet Map Server and external web
sites to study habitat alterations to the Black, Cedar, and Duwamish Rivers in the
south Seattle area.
11/24 B Lab 8 (SAL). DHSVM Big Beef Ck
This lab has two purposes: (1) Give a general understanding of what in involved in
constructing a research-quality computer simulation model (DHSVM) of a
component of a natural ecosystem. (2) Learn specific details about the hydrology of a
Puget Sound watershed under different conditions, as revealed by the results of the
DHSVM.
12/1 B
Lab 9 (SAL). SHIRAZ Big Beef Ck
Today we learn about SHIRAZ (Salmon Habitat Integrated Resource Analysis:
Zowie!), a salmon life-cycle model that incorporates anthropogenic effects into fishhabitat relationships. It allows for future projections of salmon population sizes as
affected by habitat variables
12/8 B
Lab 10 (FT 4). West Point Treatment Plant
Today we will examine the overall issues in the treatment of sewage, from
collection to dispersion (or “where does it all go”...).

The Hydrologic Cycle as Defining Framework
P (precipitation) = Q (runoff) + ET (evapotranspiration) + SM (soil moisture/GW)
One of the most significant challenges for
evaluation of past performances and especially for
laying the basis for future decisions is how to
analyze, in a quantitative manner, the multiple
complex pathways and tradeoffs involved in policy
project and design in watersheds, from small to
regional….

For our opening lab, we will do a “virtual” exploration of Puget Sound, learning
about what “attributes” are where. And begin to become familiar with “spatial

Introducing ArcIMS and Puget Sound
ArcIMS (Arc is a brand name, IMS stands for Internet Map Server) is a computer software system that
allows display and manipulation of Geographic Information System (GIS) map data using a web browser (sort
of like Google Earth). Many “layers” of geographic information have been prepared in advance for our labs.
We will use ArcIMS to mix-and-match various views of the Puget Sound Ecosystem and to study its
properties.
