Oscars questions from email
Fe soures quantified? Trajectories?
Bouayancy winds, glacial melt?
rob
Profound freshening ross and amundsen
seas..jacobs articles and orsi
Sea ice region…issue of interpolation of
trajectories of floats… SOCCOM will not
have funds for sound sources to track
floats
Ralph
Gas exchange and atmosphere
observations to complement soccom
ships etc
What are you after for carbon
balance? Anthropogenic carbon? How
separate? Methods for s. ocean do not
work so well
Models..bgc ecosystem
Scales…
Smaller scales more local..depend on
where…must define where based on
why
Upper ocean 300 m to depth of
seasonal mixing to depth of winter
mixing and always physics base of
mixed layer
Add to global state of art…
Winter…deep water formation affects
global ocean
Process cruises diverse provinnces
different biogeochem / communities
WAP transect ross sea in winter?
Polyna?? Gliders?? Large transition
zones east of peninsula
West of peninsula George VI ice shelf
source of fresh water
Iron ?? let that not drive the bus! Bg
questions but answering them not
easy..will take all funds! Include Fe in
cruises, depend on others for larger
distribution, we focus on processes Fe
and biology Fe seasonal element…not
just how much but when,
where…glacial melt deliver to surface
SAM ENSO and interaction of these
waves other cycles?? And regulation of
present day and how those may change
in future mode 3?? Locally may have
no SAM 6 year cycles seens in WAP
capacityof SO to sequester CO2 now
and in future..is it Fe dependent? How
quantify? What will imit after Fe is it
light?? Clouds, mixing depths….??
Grazing???
How integrate floats, process, surveys
atmosphere, models satellite…..what
are inadequacies and how
Soccom gaping holes not uniform
samplers..will go where currents take
them…fronts that floats may not cross
so need cross gradient high resolution
Gap analysis weakneses and strengths
of different modalities
Scale, export can be small scale but
large scale observations do not
resolve..pancake ice robs talk
images,,,krill, zooplankton salps
patchy
Non steady state…pulse modality
Linked to EXPORTS…siegle and
buessler
So far based on what we know…how
do we go beyond that…NCP not clear
how to go about this…what is
NCP,..methods (cf EXPORTS)..what
will we do new or better to change the
Do not be too process oriented..focus
focus focus..not grab bag like
JGOFS..spatial and temporal footprint
that lasts longer….long duration
gliders
Do not wait for PACE for Satellite
push the current time series now!
Synthesis of satellite, models, obs etc.
now
