Abstract
The circulation of the deep ocean at the Last Glacial Maximum (LGM) is a crucial piece of the puzzle to understand past
variations in CO2 and glacial-to-interglacial cycles more generally. In the modern ocean, we use the patterns of temperature
and salinity to map the distribution of deep-water masses. In addition, these values inform the balance of air-sea exchange
processes that are required to form deep water in the first place. They are an integrated record of climate at high latitudes.
For the LGM a full T-S plot has remained elusive. However, sampling deep ocean sediments for their interstitial fluids, and
then measuring 18O and [Cl] on the water, can provide a record of these tracers that has been advectively and diffusively
altered since the LGM. With local benthic 18O data, the pore water information can be turned into a single point on the LGM
T-S diagram for a single profile. The current version of this plot, from sampling IODP material, contains only four points, but
they are very interesting. Most of the ocean lies close to the freezing point at the LGM and there seems to be a larger deep
stratification that is salinity driven. Most surprisingly, the salt gradient in the modern Atlantic of fresh southern sourced waters
and salty northern sourced waters, seems to have flipped at the LGM. The saltiest waters were formed around Antarctica.
In the years since this early work, we have improved the analytical measurement of [Cl], attempted several new sampling
strategies aimed at increasing throughput, and improved the data analysis tools we use to model the data. The next most
important step in constraining the temperature, salinity, and density structure of the LGM deep ocean is to obtain depth
transects of these properties. Samples taken from the same region of the ocean, but spanning from the bottom of the ocean
to the base of the main thermocline would greatly constrain the processes that could fill the LGM deep ocean and control its
circulation. To this end, we propose to add 150 meter deep holes to several of the proposed sites in the SAFARI cruise to the
Agullas Current system. This work would extend the total time of the cruise by less than 10% and represent a significant
value added to both the specific cruise objectives and the wider paleo community.

Scientific Objectives
We hope to drill an extra 150 meter hole for dedicated pore water sampling at four of the primary sites proposed in the
SAFARI cruise to the Agullas Current system. If time allows 2 of the deeper secondary sites are also desirable.
Non-standard measurements technology needed to achieve the proposed scientific objectives.
Our procedures follow standard IODP protocol for cutting whole rounds and squeezing pore fluids. However, we are
interested in high-resolution samples, with a point every 1.5 meters, or every 1 meter if possible. Our plan is to measure [Cl]
and d18O back on shore, but we are happy to have some of this water used for the regular IODP interstitial fluid analysis.

The Density profile of the LGM Ocean from a range of depths in the Agulhas Current system. Temperature and Salinity of the Deep Ocean The temperature and salinity distributions in the modern deep ocean are not homogeneous, but are instead organized into differnent water masses. For all depths below 2000m that fall between the σ2 density class of 37.0-­‐37.235 there are large temperature and salinity differences (Figure 1). Deep-­‐water mixing trends develop from the surface boundary fluxes of heat and fresh water at high latitudes. North Atlantic Deep Water (NADW) is salty because a component of the sinking water around Greenland comes from lower latitudes waters of the Gulf Stream and North Atlantic Drift current systems. In contrast, around Antarctica the presence of the Drake Passage isolates the southern deep-­‐
water formation regions from saltier lower latitude waters in the gyres. In addition, the large, land based ice sheet on the Antarctic continent calves and melts into the very regions where deep water is forming, leaving it fresher than NADW. The modern deep T-­‐S plot is a direct view into the surface boundary fluxes, and therefore climate, of the deep-­‐water formation regions. Measuring the T-­‐S plot for the past ocean would give us a direct view into the workings of the deep ocean circulation. As the locus of nearly all the carbon in the ocean-­‐
atmosphere system, the circulation pattern and ventilation rate of the deep is crucial for understanding how climate cycles between glacial and interglacial states [Hain et al., 2010; Sarmiento and Toggweiler, 1984; Toggweiler, 1999]. Constructing a T-­‐S plot for the LGM from sediment proxy data is easier for temperature Figure 1: T/S plot for the modern deep ocean. Data are filtered from than for salinity. There the Glodap database for σ2 values between 37.0 and 37.235. are a variety of promising temperature tracers in Mg/Ca [Elderfield et al., 2006], clumped isotopes [Ghosh et al., 2006], and the combination of δ18O in foraminifera and sea level [Chappell and Shackleton, 1986; Cutler et al., 2003]. However, there are no viable salinity tracers in the modern geochemical toolbox. Dinoflagelate transfer functions show some promise for surface waters where there are relatively large signals [de Vernal et al., 2001], but the deep ocean has no proxies as of yet. Using Pore Water Profiles to Get T and S at the LGM Following the pioneering work of Russ McDuff [McDuff, 1985], we can use the modern profiles of δ18Ow and [Cl] in sediment pore fluid, and a vertical diffusion-­‐advection equation, to measure LGM values of both tracers (Figure 2). Recognizing that better data was needed, Figure 2: Two of our previously published Atlantic pore water profiles for [Cl]. The percent change should be viewed relative to a global mean value of ~3.5%. Both cores show good agreement at the sediment-­‐water interface and at the remnant LGM peak. One hope in this proposal is to reduce the scatter and increase the depth resolution of these plots. Schrag et al. measured δ18O at high precision and high depth resolution in the Equatorial Atlantic [Schrag et al., 1996]. These data suggested a much smaller change in δ18O due to continental ice sheets than previously thought [Fairbanks and Matthews, 1978], and thus implied a larger role for bottom water temperature changes in the benthic foram δ18O from the same cores. These results have been confirmed with more cores and indicate that deep ocean temperatures were near the freezing point at the LGM. With a core collection that spanned much of the modern deep ocean salinity gradient, we then made the first T-­‐S plot for the LGM deep ocean [Adkins et al., 2002] (Figure 3). Getting the samples to add more points to this plot is one principle goal of the current proposal. While limited in the total number of points, the geographical spread in the T-­‐S plot reveals several interesting features. Points at the LGM that were largely separated by their Figure 3: T/S plot for the LGM. Based on the type of pore water data we propose to collect here, this plot shows several differences with the modern (described in the text). Yellow dots are the location of modern bottom waters where the cores for the blue LGM points were collected. The ODP site numbers and gray isopycnals provide context. temperature differences in the modern are now spread apart by their salinity differences. As most of the ocean seems to be at or near the freezing point, salinity is the dominant control on deep-­‐water density. In addition, the salt gradient in the Atlantic flipped at the LGM. Southern source waters are the saltiest in the ocean, while northern source waters appear to be the freshest. This drastic rearrangement of the deep water T/S implies some very different surface water forcing functions in the LGM deep-­‐water formation zones. Exploring the implications of this T-­‐S diagram has been a thrust of the Adkins research group for the last several years [Adkins, 2013; Lund et al., 2011; Miller et al., 2012], but what is most important in the near future is to gather more data. To date, we have used the standard methods of the Ocean Drilling Program [Gieskes et al., 1991] to recover pore fluids from sediments. We have tested Rhizon sampling on Leg XXXX and found a systematic increase in the δ18O and [Cl] compared to conventionally squeezed samples. Recently at Caltech we have improved the titration method for [Cl] analysis to be fully digital and have begun to use more sophisticated data analysis tools to explore the range of bottom water histories that the 1-­‐D model will allow given the pore water data. This Baysian Markov Chain/Monte Carlo approach has been part of the thesis work of Madeline Miller, for which she recently won the best poster award at ICP 11. The key is that we can relax the constraint of following the shape of the global mean sea level curve for our bottom water forcing function. The data collection and data analysis are both poised to greatly improve our understanding of the information content contained in pore water profiles. Depth Organized Samping; The Importance of Profiles Figure 4. Holocene and LGM depth transects of benthic foraminifera δ18O at the Blake Ridge, ~30°N in the Western Atlantic (from [Keigwin, 2004]). Circles are Cibicidoides sp. and triangles are Uvigerina, adjusted for their species offset. Notice the distinct kink at ~2,000m in both species at the LGM, but not in the Holocene. In the modern ocean, oceanographers use the buoyancy flux at the surface where deep isopycnals outcrop to analyze circulation rates. However, most paleo data is more easily structured in depth coordinates than in density space. In the 1960s Walter Munk presented a solution to this problem in a 1-­‐D balance of vertical diffusion and advection he called ‘Abyssal Recipes’ [Munk, 1966]. In this work, a profile of a conservative tracer constrains the ratio of upwelling to vertical diffusion at that site. The Δ14C profile adds a second constraint with no new unknowns and allows for the separation of the upwelling/diffusion ratio into its component parts. The key is an assumption that the ocean behaves as a one-­‐dimensional fluid, something we clearly know is not the case today. However, Munk’s numbers of 1x10-­‐4 m2/s and ~4 meters/yr, for vertical diffusivity and a global upwelling rate respectively, have stood the test of time. Our proposed pore water sampling can collect the T and S information a Munk like analysis needs to constrain the past circulation. As a proof-­‐of-­‐concept, we have shown how the δ18O of benthic forams themselves are a conservative tracer, even without separation into temperature and δ18O w/salinity/ice volume components [Lund et al., 2011]. Several profiles of benthic δ18O in the LGM Atlantic [Curry and Oppo, 2005; Keigwin, 2004] and Indian [Kallel et al., 1988] have a distinct kink at ~ 2000 meters water depth (Figure 4). For a conservative tracer this sharp vertical gradient represents a water mass boundary. We constructed a whole water mass conservative tracer mass balance, rather than just a 1-­‐D balance as in ‘Abyssal Recipes’, using this demarcation for the upper lid of northward flowing southern source water [Lund et al., 2011]. The amount of δ18Obenthic in the water mass north of 30°S can only change via transport of tracer into the volume (equivalent to the physical oceanographer’s overturning stream function) and the diffusion of tracer across the water mass boundary defined by the vertical δ18O benthic kink. The difference from Munk’s approach is that now we are constraining the ratio of tracer transport to tracer diffusion across the whole water mass, rather than assuming a local 1-­‐D balance. Comparing the modern and LGM tracer balances in this way, we found that the ratio of transport to diffusion increased at the LGM by a factor of ~8, with a minimum change (given the errors involved) of a factor of 2. As it is hard to imagine the circulation of the deep-­‐sea having the energy to spin eight times faster [Ferrari and Wunsch, 2009], we interpret this result as a dramatic drop in the vertical diffusivity of tracer between the northern and southern LGM deep-­‐water masses. A major open question from this work is whether there is a deep pycnocline corresponding to this water mass boundary seen in benthic δ18O. Vertical profiles of T and S from the pore water method would clearly test this idea. Proposal We propose to combine the power of pore water sampling for δ18O and [Cl], with the inherent advantages of organizing these samples into a depth transect. The next most important step for the LGM T-­‐S plot is to collect a profile of cores from similar locations. The SAFARI cruise to the Agulhas Current system represents an opportunity to fulfill these goals. With present water column depths of 380, 2050, 2671, and 3040 meters in the primary cores, and possibly 2700-­‐2800 and 3600 meters in the secondary cores (Table 1), this cruise is an excellent opportunity to move the LGM distribution of heat and salt forward. We propose to add an extra hole at each of the primary sites listed below and 1-­‐2 of the secondary sites depending on which ones get drilled. These holes would be for dedicated pore water sampling and only require 150 meters of sediment. At each location we only propose 150 meters of drilling for the pore water dedicated holes. This approach should save time, but still provide ample material to squeeze samples for [Cl] and δ18O at 1-­‐1.5 meter resolution. The depth transect covers the lower half of the proposed LGM density gradient and one point in the main thermocline. While not exactly a full transect over the entire ‘kink’ in the benthic δ18O profiles, these will be an important step forward in the filling out of the LGM depth profile of temperature and salinity.
