Conservation Of Coastal Marine

Front 1

what are two prophecies that interal in the coast realm?

Back 1

processes in the ocean

&

processes on land

both interact in the coastal realm

Front 2

even though the deep water is not considered the coast why can in be important when you try to define the coast?

Back 2

LIMITED NUTRIENTS (phosphorous) provided by upwelling from deep water (which is not considered the coast)

those nutrients in that deep water affect coastal processes and vice verse

Front 3

what is a water shed?

Back 3

total area that drains to a coastal water body

Front 4

what were the four question related to the coastal realm?

Back 4

1 how should four wheeled traffic on beaches be regulated

2 how should development zoning be established for coastal waters

3 what is the extent of land area that affects coastal waters

4 who owns the resources of the coastal oceans

Front 5

what is the strict definition of the coastal realm?

Back 5

the band of dry land and adjacent marine environment in which terrestrial processes and land uses directly affect oceanic processes and uses & vice versa

Front 6

why is it hard to define the coast ?

Back 6

your going to have a different definition for what the coastal realm is . so depending on what you want to do or what your concern is with respect to the coast is going to alter how you define the coast

Front 7

what is the area of the coast disproportionate with the productivity is provides?

Back 7

although the coastal realm occupies only 0.5% of ocean volume
-25% of global PRIMARY PRODUCTION

-90% of global fish catch

-60% of human population 2 thirds of largest world's cities

you have a disproportional amount of
PRODUCTIVITY
DENITRIFICATION
CARBON STORAGE
GLOBAL FISH CATCH
AND ITS WHERE PPL WANT TO LIVE

THE COASTAL REALM HAS A DISPROPORTIONATE LEVEL OF IMPORTANCE WITH RESPECT TO ECOLOGICAL PROCESSES

Front 8

what is one of the fundamental principles that determine what type os coast line you have any where in the world?

Back 8

plate tectonics

Front 9

in a general sense all coast regions have one of two characteristics what are they

Back 9

collision coast is characterized by that deep trench and mountains along that coast line

(you have a very deep trench because you have a plate that is thrust well under the top plate)

you have very narrow continental shelfs you have a very narrow area of shelf water you have a deep ocean trench (geologically active margin)
and

trailing edge coast line (away from both the collision coast and spreading center) inactive margin

Front 10

active margin=
inactive margin=

Back 10

collision
trailing edge

Front 11

what are the characteristic of a collision coast line name 4

Back 11

1. very narrow continental shelfs
2. very narrow area of shelf under water
3 deep ocean trench
4 rugid flip of mountain ranges that brings a lot of volcanic earthquake activity

Front 12

what are the characteristics of trailing edge coast line name 3

Back 12

1. geologically stable
2 broad shallow coastal area(no mountains)
3 very large water sheep because of lack of mountains

Front 13

who does geology and meteorology influence ecology?

Back 13

geology basically determine what ecosystems develop and thus ecology that is happening with in them

Front 14

that ___ principle is the number 1 factor giving rise to the ______of coast lines

Back 14

one simple geological

specific characteristics

Front 15

water shed=drainage and is where..

Back 15

entire land area from which water would flow to single coastal water body

Front 16

active margin 3 things

Back 16

little or no shelf
steep slope
trench

wide shelf
gentle slope
continental rise

Front 17

once you have a trailing edge coast line or a collision coast line you begin to know what types of ____

Back 17

habitats you are going to have

Front 18

trailing edge coast line is dominated by theses 3

Back 18

salt marshes
mangroves
subtropical regions

because your have that long flat area over which they can develop

low mangroves and salt marshes in collision boundaries because the mountains are going right in the ocean

Front 19

at any point in time the____ is what constrains primary productivity

Back 19

most limiting factor

Front 20

the fundamental mechanism of nutrient delivery that fuels _____ in coastal regions is different on collision coast and trailing edge coast line

Back 20

primary productivity

Front 21

collision coast line has a deep trench that is generated immediately adjacent to land
what are the elements that is a one way pathway from terrestrial to aquatic environment there is NO ATMOSPHERIC COMPONENT

Back 21

PHOSPHOROUS
it is found in rocks and is essentially weathered and that phosphorous is a one way pathway from land to bottom of lands and oceans because there is NOT ATMOSPHERIC COMPONENT that can recycle that element back to land

one these deep coast lines your have
HYDROLOGICAL
CURRENT CHARACTERISTIC
that force water away from the coast line that allows cool nutrient rich waters to upwell along the coast line of collision coast

Front 22

where are the most productive fisheries in the world found?

Back 22

along collision coast lines where you have massive amounts of upwelling bringing phosphorous back to the surface which fuels primary productivity

Front 23

in collision coast lines ____processes dominate the coast

Back 23

oceanic

Front 24

what is the important take away point about collision coast lines

Back 24

that oceanic processes are driving coastal phenomenon

Front 25

in trailing edge coast lines ____processes are important in determining that ecological phenomena that are currently in the coastal zone

Back 25

terrestrial

Front 26

water sheds and drainage remember that the total land area which drains into a single coastal point

so on these trailing edge margins, coastal processes are more influenced by those things happening ___than ____

Back 26

inland than things that are happening in the adjacent ocean

Front 27

any semi enclosed coastal water body where fresh and salt water mix is a

Back 27

estuary

Front 28

WHAT IS THE COASTAL REALM?regional and local coastal characteristics determined by larger scale _____&_____processes

Back 28

both spacial and temporal geological & hydrological processes

geology: plate tectonics shaping coast lines

hydrology: fresh water impute current patterns tides

Front 29

what are four major ways estuaries are formed

Back 29

1 flood river valleys with rising sea levels
2 formation behind barrier lslands due to regional processes
3 tectonic land subsidence and faulting
4 glaciation

Front 30

many times the dollar value on these ecosystem services are not really put out there untill..

Back 30

its too late
developed until that ecosystem is gone

Front 31

___are true marine plants that have made to next evolutionary step (true marine flowering plants

Back 31

sea grasses

Front 32

sea grasses are very productive ecosystems productive plants therefore they support importort ..

Back 32

1 nusery areas
2 support high levels fishers production
3 carbon storage and fixation

Front 33

what is blue carbon

Back 33

-if you lose these plants species they are not taking out that carbon dioxied from the atmosphere
- so your getting increase levels; your not having that offset

Front 34

what can you predict with sea grass cover?

Back 34

you can predict fish productivity on a given reef

Front 35

____have a sessile adult stage, once they actually settle on the _______they dont move but you have very high levels of _____at _____

Back 35

oysters
water column
connectivity
larval stage

Front 36

oysters have a 2 month larva stage
they have _____ ____ of _____ at that larva stage

Back 36

huge distances of dispersal

Front 37

as oysters begin to settle on the water column you begin to ___

Back 37

settlement

Front 38

settlement from ______ to _____

Back 38

pelagic stage (in the water column to benthic stage(bottom)

Front 39

what is self sterotaxis

Back 39

where they can actually detect CHEMICALS of other CON SPECIFIC individuals and they actually preferentially RECRUIT to existing live oyster

Front 40

once you get oyster growing you have a ___ continuing to drive inc oyster coverage

Back 40

positive feedback cycle

Front 41

if you are perturbed from the point some internal process will bump you back to it

Back 41

neg feedback cycle

Front 42

oysters only live in
