DESCRIPTION:Title: Tracing Carbon Dynamics in the Southern Ocean and Coral R
eefs Using Strontium and Calcium Tracers\nby Yaijia Sun (RSES) as part
of ANU Research School of Earth Sciences HDR seminars\n\nLecture held in
Jaeger 1 Seminar Room.\n\nAbstract\nThe atmospheric CO2 levels has been ri
sing steadily\, reaching over 420 ppm. The ocean serves as the largest eas
ily exchangeable reservoir for carbon\, absorbing approximately 30% of ant
hropogenic emissions\, which helps mitigate impacts of climate change. Thi
s uptake is primarily driven by the biological pump\, a process that seque
sters CO2 in the deep ocean. \nIn this talk\, I will discuss two key contr
ibutors to carbon removal in the ocean: Acantharia and corals. Acantharia
are an overlooked component of marine carbon sequestration. They are proti
sts with dense skeletons made of strontium sulfate (SrSO₄). This makes t
hem an effective ballast\, enhancing the biological pump by facilitating t
he sinking of organic carbon to the deep ocean. I will specifically focus
on how Acantharia contribute to carbon sequestration in the Southern Ocean
. Additionally\, I will explore the carbon dynamics of coral reefs. In the
se ecosystems\, calcifying organisms such as corals\, crustose coralline a
lgae (CCA)\, foraminifera\, and molluscs play a significant role by produc
ing calcium carbonate (CaCO₃) skeletons. My discussion will centre on wh
ich of these organisms are experiencing dissolution and precipitation\, wi
th particular emphasis on the role of CCA in buffering the system and prot
ecting the reef from dissolution. This knowledge also aids in predicting h
ow reef ecosystems may respond to ongoing ocean acidification\, which thre
atens to slow calcification processes.\n

DESCRIPTION:Title: Interactions between meteoric\, surface\, and ground wate
r in an upland fractured rock catchment: upper Murrumbidgee\, southeastern
Australia\nby Sharon Gray (RSES) as part of ANU Research School of Ea
rth Sciences HDR seminars\n\nLecture held in Jaeger 1 Seminar Room.\n\nAbs
tract\nGroundwater is a vital resource that supports environmental and hum
an needs when surface water or rainwater are scarce. For many upland water
storages in southeastern Australia\, groundwater discharge into streams (
baseflow) provides flows that moderate dam water-level declines during dro
ught. This\, along with water restrictions and efficiency measures\, allow
ed major cities to keep the taps running during the Millenium Drought. Dur
ing the Tinderbox Drought [1]\, many major rivers had record low flows. So
me ceased to flow. This includes rivers in the Upper Murrumbidgee Catchmen
t\, that provide town water in the Canberra Region and flows to the Murrum
bidgee Irrigation District through Burrinjuck Dam. How groundwater stores
in upland fractured rock catchments can sustain stream flows during low ra
infall\, and how changes in groundwater stores will impact water use and a
vailability with population growth in a changing climate\, are crucial que
stions for the future. \nGeochemical tracers such as water stable isotopes
(δ18O/δ2H) and chloride (Cl−) can reveal groundwater movement though
fractured rock catchments. Sequential monthly precipitation composites wer
e collected from 19 samplers [2] located around the catchment from 2017 to
2019. Up to 149 surface water samples were collected during synoptic surv
eys in late 2018 and early 2019. These data were augmented using historica
l groundwater geochemistry information from public databases and prior res
earch. Samples were analysed for major ions and water stable isotopes.\nPr
ecipitation studies identified environmental controls on water stable isot
ope and dissolved solute composition\, with a local isoscape and Cl− dep
osition map providing finer resolution on catchment-wide variability than
continental-scale interpolations [3\,4]. Surface water and groundwater hyd
rochemistry revealed that mineral weathering controls dissolved solutes\,
with precipitation inputs and evaporation also contributing. It showed tha
t precipitation is the main source of water stable isotopes and Cl− for
the catchment. Water stable isotope comparison between groundwater and pre
cipitation suggests that local winter precipitation recharges groundwater.
Groundwater hydrographs show that levels are highly reactive to changes i
n precipitation amount. Cumulative deviation from the moving mean [5] reve
aled that the groundwater level lows of the Millenium and Tinderbox Drough
ts may not be unique in recent history\, and that groundwater levels in hi
gher elevation areas have recovered to pre-Millenium Drought levels at the
end of the 2020–2022 La Niña. Baseflow separation analysis [6] support
s this and reveals that baseflow has declined in some areas since the mid-
1990s. High baseflow along the western range\, with similar long-term rech
arge/precipitation and baseflow/precipitation ratios\, can be explained by
high annual precipitation and large differences between annual precipitat
ion and evapotranspiration. \nGroundwater baseflow volumes in upland fract
ured rock catchments will decline as temperatures increase and precipitati
on regimes change. Streams and water storages will become more reliant on
run-off during droughts since groundwater will have reduced capacity to su
stain stream flows. Despite this\, groundwater stores can recover when pre
cipitation returns\, and the landscape is primed for recharge. This has dr
ought-preparedness implications for surface water managers and groundwater
users in upland fractured rock catchments\, particularly if they want to
avoid a ‘boom-bust’ cycle to water availability.\n

DESCRIPTION:Title: The inner edge of the outer solar system: populations and
processes in the formation of chondrules of the carbonaceous chondrites\nby Geoff Bonning (RSES) as part of ANU Research School of Earth Scienc
es HDR seminars\n\nLecture held in Jaeger 1 Seminar Room.\n\nAbstract\nThe
chondrites are cosmic sediments that contain rich records of the processe
s that occurred during the early formation of the Solar System\, but after
over a century of study they remain “tight-lipped witnesses”. The car
bonaceous chondrites appear to represent the inner edge of the outer Solar
System\, where a barrier prevented the inward migration of outer material
\, limiting the growth and reducing the water abundances of the terrestria
l planets. This research has focused on the populations of chondrules (cry
stallized melts of dust aggregates) in three carbonaceous chondrites that
formed near this barrier. It has resulted in one of the largest multi-anal
ytic datasets on them\, including quantitative petrography\, major and min
or element chemistry\, REEs\, and oxygen isotopes. This has allowed for gl
impses of the distinct nebular environments recorded in the chondrule popu
lations in each chondrite\, as well as sub-populations within them. Simila
r environments have been observed in increasing detail in young planetary
systems over the last decade by telescopes such as ALMA and JWST. These ca
n help explain the chondrites as products of general protoplanetary proces
ses. Meanwhile\, asteroid sample return missions and the Global Fireball O
bservatory aid in identifying source regions for chondrites\, allowing for
their environments to be ‘mapped’ in the Solar System. Studying chond
rules as populations is a crucial part of understanding how planetary syst
ems in general\, and the Solar System and Earth in particular\, came to be

DESCRIPTION:Title: Insights into the zinc cycle of the Southern Ocean Sub An
tarctic Zone from ship to shore\nby Robin Grun (RSES) as part of ANU R
esearch School of Earth Sciences HDR seminars\n\nLecture held in Jaeger 1
Seminar Room.\n\nAbstract\nIron availability impacts zinc uptake and zinc
isotope (δ66Zn) composition in Southern Ocean phytoplankton\, a key compo
nent of the global ocean zinc cycle.\nLaboratory culture and field incubat
ion experiments were undertaken and linked to in situ depth profiles of di
ssolved (dZn) and particulate (pZn) zinc collected from three sites in the
Southern Ocean. For the laboratory experiments\, diatom growth rates\, ce
llular zinc accumulation\, and δ66Zn all responded to changes in iron and
zinc bioavailability. A significant increase in the cellular quota for zi
nc (expressed as zinc:phosphorous (Zn:P)) occurred upon iron limitation an
d zinc enrichment. At the same time\, δ66Zn for organic tissues became is
otopically light under high zinc and low iron concentrations. The opposite
occurred for frustule δ66Zn values. Here Δ66Znfrustule-organic for cult
ured phytoplankton became isotopically heavier under high zinc and low iro
n concentrations. For senescing and dead cells\, Zn:P declined and δ66Zn
increased\, indicating a loss of isotopically light zinc from organic matt
er. For field incubation experiments\, δ66Znfrustule was isotopically hea
vier than seawater\, except for added zinc treatments. The percentage of z
inc associated with frustule material for laboratory and field incubations
encompassed a wide range with values. Depth profiles of δ66Zn for dZn an
d pZn varied\, with dZn being isotopically lighter than pZn in low dZn con
centration subantarctic waters\, whereas the opposite occurred in polar wa
ters where dZn was isotopically heavier than pZn at higher dZn concentrati
ons.\nResults show that iron and zinc availability regulate the zinc conte
nt of phytoplankton and contribute to the δ66Zn composition of the Southe
rn Ocean\, which is propagated to other parts of the global ocean.\n
