Aquarium

100

what type of system is this?

recirculating

200

Main purpose of a stand pipe?

regulate the water level in the aquarium

300

What is the main difference between the recirculating flow through aquarium systems?

Flow through has a continuous supply of new water that passes through once only and recirculates water through the aquarium, a sump, filters, and back into the aquarium

400

Identify each part of the system

1. Aquarium

2. Stand pipe

3. filter

4. header tank

5.sump

6. pump

500

advantages of multi-stressor mesocosm facility

precise regulation of environmental conditions, independent replication, automated logging of environmental data

Trailering/Boating

100

We used the RTK to trace the edge of vegetation in Aloe Bay as an indication of shoreline position. Engineers measure shoreline position as the location of mean sea level. Why might these two approaches provide different locations for the shoreline position if measured on the same day.

plants can occur at different tidal elevations

200

When considering tracking shoreline position through time, what is the main advantage of using the edge of marsh vegetation to define shoreline position rather than a particular vertical elevation?

can identify marsh edge but not vertical elevation in historic aerial imagery

300

Which option best shows the approximate path that the trailer wheels will take compared to the truck wheels during a 90-degree left turn

B

400

Given wind and current directions, from which direction would you approach in the vessel to recover them from the water?

the left

500

why would you approach this person from that side?

to allow the boa to be held stationary despite the wind and current

Fish Sampling

100

fin count using correct notation

A II, 8

200

what two key steps can we take to ensure each replicate seine haul samples the same amount of area?

1. measure the distance the seine is pulled through the water using a rope or tape

2. use a headrope to keep the seine poles equal distance apart on all replicates

300

Identify the correctly written scientific name below:
A) Leiostomus XanthurusB) Leiostomus xanthurusC) leiostomus xanthurusD) Leiostomus XanthurusE) Leiostomus xanthurusF)  leiostomus xanthurus*1 point

E

400

name 6 problems with this figure

1. title goes below the figure

2. title too brief and uninformative 

3. no axis titles

4. no units specified

5. scientific names should be italicized

6. redundant second title in figure

500

When looking at fish descriptions in a guide book, what does DXI+I,23 mean?

D= dorsal fin

XI= first dorsal has 11 spines

I23= second dorsal has 1 spine and 23 rays

First Aid

100

What is the correct ratios of chest compressions to rescue breaths for high quality CPR?

30:2

200

What does AED stand for?

automated external defibrillator

300

Which feature would you preferentially use for identifying a fish?

dramatic external morphological features

400

 How would you expect marsh vegetation to respond to the installation of nearshore breakwaters if they are effective in reducing wave energy?

vegetation should grow seaward

500

 5 steps to always take when confronted with any First Aid situation

1. assess scene safety

2. take standard precautions

3. assess responsiveness

4. activate EMS

5. send someone for AED and First Aid Kit

Vegetation

100

What does RTK stand for?

real time kinematic

200

uses for RTK

elevation change monitoring

shoreline change monitoring

vegetation mapping

300

define Percent Canopy Cover as a metric for quantifying plants in a quadrat.

percentage of the ground surface within the quadrat that has vegetation vertically above it

400

define Stem Density as a metric for quantifying plant abundance in a quadrat.*1 point

number of stems of each species per unit area

500

main advantage of using the edge of marsh vegetation to define shoreline position rather than a particular vertical elevation

can identify marsh edge but not vertical elevation in historic aerial imagery
