DESCRIPTION:Title: Tracing Carbon Dynamics in the Southern Ocean and Coral Reefs Us
ing 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 rising st
eadily\, reaching over 420 ppm. The ocean serves as the largest easily exc
hangeable reservoir for carbon\, absorbing approximately 30% of anthropoge
nic emissions\, which helps mitigate impacts of climate change. This uptak
e is primarily driven by the biological pump\, a process that sequesters C
O2 in the deep ocean. \nIn this talk\, I will discuss two key contributors
to carbon removal in the ocean: Acantharia and corals. Acantharia are an
overlooked component of marine carbon sequestration. They are protists wit
h dense skeletons made of strontium sulfate (SrSO₄). This makes them an
effective ballast\, enhancing the biological pump by facilitating the sink
ing of organic carbon to the deep ocean. I will specifically focus on how
Acantharia contribute to carbon sequestration in the Southern Ocean. Addit
ionally\, I will explore the carbon dynamics of coral reefs. In these ecos
ystems\, calcifying organisms such as corals\, crustose coralline algae (C
CA)\, foraminifera\, and molluscs play a significant role by producing cal
cium carbonate (CaCO₃) skeletons. My discussion will centre on which of
these organisms are experiencing dissolution and precipitation\, with part
icular emphasis on the role of CCA in buffering the system and protecting
the reef from dissolution. This knowledge also aids in predicting how reef
ecosystems may respond to ongoing ocean acidification\, which threatens t
o slow calcification processes.\n

DESCRIPTION:Title: Interactions between meteoric\, surface\, and ground water in an
upland fractured rock catchment: upper Murrumbidgee\, southeastern Austra
lia\nby Sharon Gray (RSES) as part of ANU Research School of Earth Sci
ences HDR seminars\n\nLecture held in Jaeger 1 Seminar Room.\n\nAbstract\n
Groundwater is a vital resource that supports environmental and human need
s when surface water or rainwater are scarce. For many upland water storag
es in southeastern Australia\, groundwater discharge into streams (baseflo
w) provides flows that moderate dam water-level declines during drought. T
his\, along with water restrictions and efficiency measures\, allowed majo
r cities to keep the taps running during the Millenium Drought. During the
Tinderbox Drought [1]\, many major rivers had record low flows. Some ceas
ed to flow. This includes rivers in the Upper Murrumbidgee Catchment\, tha
t provide town water in the Canberra Region and flows to the Murrumbidgee
Irrigation District through Burrinjuck Dam. How groundwater stores in upla
nd fractured rock catchments can sustain stream flows during low rainfall\
, and how changes in groundwater stores will impact water use and availabi
lity with population growth in a changing climate\, are crucial questions
for the future. \nGeochemical tracers such as water stable isotopes (δ18O
/δ2H) and chloride (Cl−) can reveal groundwater movement though fractur
ed rock catchments. Sequential monthly precipitation composites were colle
cted from 19 samplers [2] located around the catchment from 2017 to 2019.
Up to 149 surface water samples were collected during synoptic surveys in
late 2018 and early 2019. These data were augmented using historical groun
dwater geochemistry information from public databases and prior research.
Samples were analysed for major ions and water stable isotopes.\nPrecipita
tion studies identified environmental controls on water stable isotope and
dissolved solute composition\, with a local isoscape and Cl− deposition
map providing finer resolution on catchment-wide variability than contine
ntal-scale interpolations [3\,4]. Surface water and groundwater hydrochemi
stry revealed that mineral weathering controls dissolved solutes\, with pr
ecipitation inputs and evaporation also contributing. It showed that preci
pitation is the main source of water stable isotopes and Cl− for the cat
chment. Water stable isotope comparison between groundwater and precipitat
ion suggests that local winter precipitation recharges groundwater. Ground
water hydrographs show that levels are highly reactive to changes in preci
pitation amount. Cumulative deviation from the moving mean [5] revealed th
at the groundwater level lows of the Millenium and Tinderbox Droughts may
not be unique in recent history\, and that groundwater levels in higher el
evation areas have recovered to pre-Millenium Drought levels at the end of
the 2020–2022 La Niña. Baseflow separation analysis [6] supports this
and reveals that baseflow has declined in some areas since the mid-1990s.
High baseflow along the western range\, with similar long-term recharge/pr
ecipitation and baseflow/precipitation ratios\, can be explained by high a
nnual precipitation and large differences between annual precipitation and
evapotranspiration. \nGroundwater baseflow volumes in upland fractured ro
ck catchments will decline as temperatures increase and precipitation regi
mes change. Streams and water storages will become more reliant on run-off
during droughts since groundwater will have reduced capacity to sustain s
tream flows. Despite this\, groundwater stores can recover when precipitat
ion returns\, and the landscape is primed for recharge. This has drought-p
reparedness 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 proces
ses in the formation of chondrules of the carbonaceous chondrites\nby
Geoff Bonning (RSES) as part of ANU Research School of Earth Sciences HDR
seminars\n\nLecture held in Jaeger 1 Seminar Room.\n\nAbstract\nThe chondr
ites are cosmic sediments that contain rich records of the processes that
occurred during the early formation of the Solar System\, but after over a
century of study they remain “tight-lipped witnesses”. The carbonaceo
us chondrites appear to represent the inner edge of the outer Solar System
\, where a barrier prevented the inward migration of outer material\, limi
ting the growth and reducing the water abundances of the terrestrial plane
ts. This research has focused on the populations of chondrules (crystalliz
ed melts of dust aggregates) in three carbonaceous chondrites that formed
near this barrier. It has resulted in one of the largest multi-analytic da
tasets on them\, including quantitative petrography\, major and minor elem
ent chemistry\, REEs\, and oxygen isotopes. This has allowed for glimpses
of the distinct nebular environments recorded in the chondrule populations
in each chondrite\, as well as sub-populations within them. Similar envir
onments have been observed in increasing detail in young planetary systems
over the last decade by telescopes such as ALMA and JWST. These can help
explain the chondrites as products of general protoplanetary processes. Me
anwhile\, asteroid sample return missions and the Global Fireball Observat
ory aid in identifying source regions for chondrites\, allowing for their
environments to be ‘mapped’ in the Solar System. Studying chondrules a
s populations is a crucial part of understanding how planetary systems in
general\, and the Solar System and Earth in particular\, came to be.\n

DESCRIPTION:Title: Insights into the zinc cycle of the Southern Ocean Sub Antarctic
Zone from ship to shore\nby Robin Grun (RSES) as part of ANU Research
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 component of
the global ocean zinc cycle.\nLaboratory culture and field incubation exp
eriments were undertaken and linked to in situ depth profiles of dissolved
(dZn) and particulate (pZn) zinc collected from three sites in the Southe
rn Ocean. For the laboratory experiments\, diatom growth rates\, cellular
zinc accumulation\, and δ66Zn all responded to changes in iron and zinc b
ioavailability. A significant increase in the cellular quota for zinc (exp
ressed as zinc:phosphorous (Zn:P)) occurred upon iron limitation and zinc
enrichment. At the same time\, δ66Zn for organic tissues became isotopica
lly light under high zinc and low iron concentrations. The opposite occurr
ed for frustule δ66Zn values. Here Δ66Znfrustule-organic for cultured ph
ytoplankton became isotopically heavier under high zinc and low iron conce
ntrations. For senescing and dead cells\, Zn:P declined and δ66Zn increas
ed\, indicating a loss of isotopically light zinc from organic matter. For
field incubation experiments\, δ66Znfrustule was isotopically heavier th
an seawater\, except for added zinc treatments. The percentage of zinc ass
ociated with frustule material for laboratory and field incubations encomp
assed a wide range with values. Depth profiles of δ66Zn for dZn and pZn v
aried\, with dZn being isotopically lighter than pZn in low dZn concentrat
ion subantarctic waters\, whereas the opposite occurred in polar waters wh
ere dZn was isotopically heavier than pZn at higher dZn concentrations.\nR
esults show that iron and zinc availability regulate the zinc content of p
hytoplankton and contribute to the δ66Zn composition of the Southern Ocea
n\, which is propagated to other parts of the global ocean.\n
