(E4) Use #4: Exploring Coastal Upwelling
Goals
Understand how scientists ment control in environ tops, azimuth inclinations, and quadrant inclinations.
Investigate the sympathy betwixt curves, deportment floatings, sea deportment region and upwelling and
downwelling.
• Determine if upwelling or downwelling was occuring concurrently the Pacific Northwest seashore in September of 2013.
Seasonal upwelling is a very dignified regularity not exacteous to the Pacific Northwest but to numerous seashoreal regions in the universe. During the summer in the Northern Hemisphere, upwelling is animaten by curves blowing from the North to the South (Northerlies) that, entirely delay the Coriolis Effect, shove deportment soak off-shore and out to sea.
Upwelling pulls heartfelt sea soak up to the deportment making the deportment seashoreal sea more salty, deliberate, and nutrient superb. The borrowed nutrients in the glowing deportment soaks trigger accelerated phytoplankton augmentation and reiter-ation, which is the cheap of the livelihood web and supports the dignified fisheries concurrently the West Seashore of the US.
To appraise and ment referring-to controls on Earth, scientists use environ tops, azimuth inclinations, and quadrant inclinations. This appraisement regularity appraises spiritless controls, as if you were in the air looking down at a level deportment. Take a few minutes to resurvey these instrument on environ tops, azimuth inclinations, and quadrant inclinations:
The symbol adown summarizes these three regularitys by giving the colonization of the red notability using each regularity.
Compass top: SE Azimuth Bearing: 140° Bearing: S40°E

Once you comprehend the dissonance betwixt the three regularitys (environ tops, azimuth inclinations, and quandrant
bearings), total the use adown.
On the artfulness of a environ to the exact, feign that “A” is nothing degrees. List the environ top, azimuth inclination, and quandrant inclination of lore V, W, X, Y, and Z.

If you deem you comprehend environ controls, you may go on to the instant allot of this use
Our balanceall motive for this use is to vindication the interrogation: In delayed September 2013, was upwelling occurring on the Pacific Northwest seashore?
We achieve resurvey indicators of upwelling using postulates from NOAA. We achieve then synthesize those indicators to mention if upwelling is occurring. Questions that you achieve vindication in Tests & Surveys for this use are numbered adown and evinced in bold, italicized passage adown.
Columbia River
Stonewall Bank Port St Georges
California
We achieve resurvey diverse postulates sources for this use. We achieve resurvey postulates from September 2013 for three NOAA eslow stations: Stonewall Bank, Port St Georges, and the Columbia River Bar. The near colonization of these elates is highlighted on the map to the exact. For your retirement, the eslow postulates you achieve use is interposed at the end of this use. You do not bear to mark the links balancehead for this use, probable you are assiduous in appearance the postulates sources.
We achieve besides resurvey maps of sea floating control off the seashore of Oregon. The postulates you achieve resurvey is from this site: Surface Currents Of The Oregon Coastal Ocean. For your retirement, the map you achieve use is interposed at the end of this use. You do not bear to mark the links balancehead for this use, probable you are assiduous in appearance the postulates sources.

Indicator #1: Curve Control
As we well-informed in our passage readings, curve control is an dignified animater of seaic upwelling. Delight resurvey this concept on page 211, symbol 7.12, of your passagebook.
6) What curve control, referring-to to the shoreline, is indulgent for upwelling concurrently the west seashore of North America?
Towards the seashore
Away from the seashore
Parallel to the seashore and blowing north
Parallel to the seashore and blowing south
7) Given your vindication to the antecedent interrogation, what control is this in azimuth degrees on a environ?
a. 0°
b. 90° c. 180° d. 270°
The three graphs on pages 7 through 9 of this worksheet show curve control balance five days for our three colonizations. The notability in the better left cavity of each map corresponds to the notabilitys on the map on the antecedent page. [Green: Columbia River, Blue: Stonewall Bank, Red: Port St Georges.] Larger accounts of these graphs are besides linked on the Use #4 page of Module (7) in Canvas. Take a few minutes to orient yourself delay the postulates shown on each graph.
8) What shifting is displayed on the x-axis (horizontal, concurrently the foot) of each graph? ___________________ 9) What shifting is displayed on the y-axis (vertical, concurrently the left aspect) of each graph? ______________________ 10)What does the sky sky sky blue continuity of each graph denote? ___________________________________________________________________
Using the graphs of curve control for each colonization on pages 7-9 of this worksheet, delight vindication the forthcoming interrogations:
11)What is the middle curve control, in degrees, for each colonization? To mention the middle, disown any superior fluctuations such as those on 9/21 and 9/24, and chronicles the prize that is most beggarly on the graph.
Columbia River Middle Curve Direction______________
Stonewall Bank Middle Curve Direction______________
c. Port St. Georges Middle Curve Control _____________
Columbia River Middle Curve Direction______________
Stonewall Bank Middle Curve Direction______________
c. Port St. Georges Middle Curve Control _____________
12)Referring to a compass, such as this one, convert the degrees balancehead to a environ top (letters).
13)Does the operative middle curve control at these colonizations evince that upwelling may be occurring? Why or why not?______________________________________________________________________________________________

Indicator #2: Deportment Currents
Surface floatings, animaten by curves and Ekman Transport, animate upwelling and downwelling. Delight resurvey this concept on page 211, symbol 7.12, of your passagebook and vindication the forthcoming interrogations.
14)In areas of upwelling, deportment floatings propose __________________ the seashore. a. Away from
b. Towards
The statue on page 10 of this worksheet shows the control and despatch of deportment floatings concurrently the Pacific Northwest. On the map, the peraccount of the triangles evinces despatch and the arrows evince control. A larger account of this statue is on page X of this use. A larger accounts of this map is besides linked on the Use #4 page of Module (7) in Canvas.

b. Warm
22) The sea region instantly concurrently the northwest Pacific Seashore is _____________________ than that of the excluded Pacific Ocean.
a. Warmer
b. Colder
23) Does the soak region concurrently the northwest Pacific Seashore evince that upwelling may be
occurring? Why or why not? __________________________________________________________________________________________ ______________________________________________________________________________________________________________________________
