<p>There aren’t many circumstances that require looking into the future to decide what people will be interested in about the past, while writing in the present. Dr. Roz Coggan wasn’t kidding when she drew a picture of a scientific ocean drilling vessel and labelled it as a Time Machine! So how do we go about communicating the science in the sediments, the cliff-hangers in the cores?</p><p>Since 1966, the scientific community has looked to the oceans, and the natural laboratories hidden beneath them, to answer fundamental questions concerning the composition, structure, and key processes of the Earth, unravelling geochemical, biological, physical, structural, climatic and geohazard-related complexities along the way. As the current phase of scientific ocean drilling (IODP) is drawing to an end, an international team has drafted a new vision for the future of this inspiring and unique program, released officially in Fall 2020.</p><p>The 2050 Science Framework for Scientific Ocean Drilling consists of seven Strategic Objectives and five Flagship Initiatives. Spanning all of these are four Enabling Elements - key facets that facilitate research activities, enhance outputs, and maximise their impact. Enabling Element 1 covers the broader impacts and outreach associated with scientific ocean drilling, including highlighting the societal relevance of its research topics, inspiring and training the next generation of ocean scientists, addressing knowledge sharing and collaborations, and working towards greater diversity and inclusion in geoscience. These are not small issues to address, and overall Enabling Element 1 sets an aspirational target for science communication going forward:</p><p>“Using a variety of social media and web-based platforms, data and results will be broadly disseminated to educators, policymakers, and the public, securing scientific ocean drilling’s position as the authoritative source of information about the Earth system.” (Koppers and Coggon, 2020)</p><p>We believe that with such broad aims, now is the time to formulate large-scale strategies for science communication. By bringing in aspects of strategy and branding, stirred together with a good dose of umbrella narratives, we aim to develop a transmedia approach to science communication, taking different present audiences on unique journeys into the past with an eye on the future. We will need to assess framing and relevance, the power of storytelling to communicate facts, and how best to ensure that our activities contribute to excitement about learning the unfolding stories of the Earth. Now is the perfect time to initiate this effort, and it is hoped that this review of multiple aspects of Science Communication, Public Engagement and branding can help begin these discussions.</p><p>“What is it that we human beings ultimately depend on? We depend on our words. We are suspended in language. Our task is to communicate experience and ideas to others”.

Abstract. Improvements in our capability to reconstruct ancient surface-ocean conditions based on organic-walled dinoflagellate cyst (dinocyst) assemblages from the Southern Ocean provide an opportunity to better establish past position, strength and oceanography of the subtropical front (STF). Here, we aim to reconstruct the late Eocene to early Miocene (37–20 Ma) depositional and palaeoceanographic history of the STF in the context of the evolving Tasmanian Gateway as well as the potential influence of Antarctic circumpolar flow and intense waxing and waning of ice. We approach this by combining information from seismic lines (revisiting existing data and generating new marine palynological data from Ocean Drilling Program (ODP) Hole 1168A) in the western Tasmanian continental slope. We apply improved taxonomic insights and palaeoecological models to reconstruct the sea surface palaeoenvironmental evolution. Late Eocene–early Oligocene (37–30.5 Ma) assemblages show a progressive transition from dominant terrestrial palynomorphs and inner-neritic dinocyst taxa as well as cysts produced by heterotrophic dinoflagellates to predominantly outer-neritic/oceanic autotrophic taxa. This transition reflects the progressive deepening of the western Tasmanian continental margin, an interpretation supported by our new seismic investigations. The dominance of autotrophic species like Spiniferites spp. and Operculodinium spp. reflects relatively oligotrophic conditions, like those of regions north of the modern-day STF. The increased abundance in the earliest Miocene of Nematosphaeropsis labyrinthus, typical for modern subantarctic zone (frontal) conditions, indicates a cooling and/or closer proximity of the STF to the site . The absence of major shifts in dinocyst assemblages contrasts with other records in the region and suggests that small changes in surface oceanographic conditions occurred during the Oligocene. Despite the relatively southerly (63–55∘ S) location of Site 1168, the rather stable oceanographic conditions reflect the continued influence of the proto-Leeuwin Current along the southern Australian coast as Australia continued to drift northward. The relatively “warm” dinocyst assemblages at ODP Site 1168, compared with the cold assemblages at Antarctic Integrated Ocean Drilling Program (IODP) Site U1356, testify to the establishment of a pronounced latitudinal temperature gradient in the Oligocene Southern Ocean.
