Q

why do oceans have thermic gradients

A

the oceans (like the rest of the earth) doesnt receive energy equally
it depends on latitude - eartth rotation and translação

Q

congelamento do mar resulta

A

maior salinidade temporaria e local

20
Q

+ temp no mar =

A

+ dilatação da água
+ degelo
=
+ volume
= subida nivel mar

21
Q

circ termohalina depende

A

densidade = temp e salinidade

22
Q

conveyor belt motor

A

circ termohalina

23
Q

o que é o conveyor belt

A

circulação prof liga todos os oceanos
1 to 2 thousand years

24
Q

componentes circ termohalina

A

força termica: + temp low lat; - temp high lat

força halina: + veap = +sal em low lat; - sal em high lat

25
Q

ciculação artico definida

A

pela circulação termica

26
Q

Água Atlântica de Fundo como se forma

A

Arctic is colder, + sline and + dense than the rest of Atlantic (diff na sal e temp)
=

sinking + mov to equator

27
Q

circulação termohalina sinonimo

A

correia transportadora

28
Q

motor circulação prof

A

Água Atlântica de Fundo

29
Q

Upwelling de aguas profundas leva

A

+ nutrientes e gases (devido – temp) = + vida

30
Q

o que é NAO

A

high and low pressure areas shifting
Resulta da redistribuição de massas de ar
tem variabilidade
Não conseguimos definir ciclicidade

31
Q

porque NAO varia

A

interação oceano <-> atmosf

32
Q

fase + NAO

A

diff entre alta e baixa pressão + que normal (+ pressão baixa e + p alta)

tempo + ameno N Eu;
tempo + frio e seco S Eu;

33
Q

temperaturas altas no arctic pode provocar

A

alt formação Água Atlântica de Fundo (se gelo derreter todo)

red tide de dinofalgellados

34
Q

que traços o oceano deve ter com onu

A

clean
resilient
productive
safe
well observed
documented
predictable

35
Q

objectives of the un decade

A

generate scientific knowledge to create a sustainable development

provide data and inform policies

36
Q

Un decade - transparent and accessible ocean

A

open access to ocean data
deliver data and information to stakeholders

37
Q

what are the societal outcomes of the decade

A

clean ocean
healthy and resilient
predictable
safe
sustainably harvested and productive
transparent and accessible

38
Q

Un decade - healthy and resilient

A

protected ocean
improved info
improved appreciation of economic and societal value
well managed

39
Q

Un decade - clean ocean

A

id and removal f pollution and sources
recycling, improved
waste management, and strengthening the governance regimes

40
Q

Un decade - predictable

A

that we can study and predict so we live well and prepared

41
Q

Un decade - safe ocean

A

protect ocean from hazards
minimize impact
integraded aproach

42
Q

Un decade - sustainably harvested

A

provides food supplies
responsibly fished
true sustainable blue economy

43
Q

Un decade - transparent

A

open access to info and data
deliver it to public and stakeholders

44
Q

NO HEMISFERIO NORTE
- ar quente — roda para a —-
- ar frio —-roda para a —-

A

NO HEMISFERIO NORTE
- ar quente sobre roda para a direita
- ar frio desce roda para a esquerda

45
Q

what makes surface currents

A

earths mov + sun heat gradient = high and low pressures = winds = air friction + Coriolis = currents
