AbstractBathymetry data are fundamental ocean observations that are important for a variety of applications including exploration and research, habitat mapping, resource management, coastal and ocean resilience, and policy decisions. Despite the importance of these data, the majority of the ocean, and our planet, remains unmapped. As a result, we lack comprehensive integrated data and information products at the resolutions necessary to address fundamental questions about subaqueous environments. With the increasing availability of mapping technology, advances in computing and data science, and an evolving culture that embraces data sharing, there are new opportunities to produce high-quality, publicly available, integrated bathymetry data products. Coordinated efforts with grand aspirations to completely map the world's oceans come at a pivotal time as we confront global challenges related to a changing planet. Through coordination and collaboration across communities, scales, and sectors, we can accelerate toward delivering data and information products that are useful to society while developing strong collaborative relationships that will have long-lasting effects. The technical and collaborative approaches developed for completely mapping the world ocean can be applied to systematic mapping efforts in other subaqueous environments and can benefit initiatives such as Lakebed 2030.

Here, I examine some of the many varied ways in which sustained global ocean observations are used in numerical modelling activities. In particular, I focus on the use of ocean observations to initialize predictions in ocean and climate models. Examples are also shown of how models can be used to assess the impact of both current ocean observations and to simulate that of potential new ocean observing platforms. The ocean has never been better observed than it is today and similarly ocean models have never been as capable at representing the real ocean as they are now. However, there remain important unanswered questions that can likely only be addressed via future improvements in ocean observations. In particular, ocean observing systems need to respond to the needs of the burgeoning field of near-term climate predictions. Although new ocean observing platforms promise exciting new discoveries, there is a delicate balance to be made between their funding and that of the current ocean observing system. Here, I identify the need to secure long-term funding for ocean observing platforms as they mature, from a mainly research exercise to an operational system for sustained observation over climate change time scales. At the same time, considerable progress continues to be made via ship-based observing campaigns and I highlight some that are dedicated to addressing uncertainties in key ocean model parametrizations. The use of ocean observations to understand the prominent long time scale changes observed in the North Atlantic is another focus of this paper. The exciting first decade of monitoring of the Atlantic meridional overturning circulation by the RAPID-MOCHA array is highlighted. The use of ocean and climate models as tools to further probe the drivers of variability seen in such time series is another exciting development. I also discuss the need for a concerted combined effort from climate models and ocean observations in order to understand the current slow-down in surface global warming.

AbstractSubsurface chlorophyll maxima are widely observed in the ocean, and they often occur at greater depths than maximum phytoplankton biomass. However, a consistent mechanistic explanation for their distribution in the global ocean remains lacking. One possible mechanism is photoacclimation, whereby phytoplankton adjust their cellular chlorophyll content in response to environmental conditions. Here, we incorporate optimality-based photoacclimation theory based on resource allocation trade-off between nutrient uptake and light harvesting capacity into a 3D biogeochemical ocean circulation model to determine the influence of resource allocation strategy on phytoplankton chlorophyll to carbon ratio distributions. We find that photoacclimation is a common driving mechanism that consistently explains observed global scale patterns in the depth and intensity of subsurface chlorophyll maxima across ocean regions. This mechanistic link between cellular-scale physiological responses and the global scale chlorophyll distribution can inform interpretation of ocean observations and projections of phytoplankton responses to climate change.

AbstractComputational Oceanography is the study of ocean phenomena by numerical simulation, especially dynamical and physical phenomena. Progress in information technology has driven exponential growth in the number of global ocean observations and the fidelity of numerical simulations of the ocean in the past few decades. The growth has been exponentially faster for ocean simulations, however. We argue that this faster growth is shifting the importance of field measurements and numerical simulations for oceanographic research. It is leading to the maturation of Computational Oceanography as a branch of marine science on par with observational oceanography. One implication is that ultra-resolved ocean simulations are only loosely constrained by observations. Another implication is that barriers to analyzing the output of such simulations should be removed. Although some specific limits and challenges exist, many opportunities are identified for the future of Computational Oceanography. Most important is the prospect of hybrid computational and observational approaches to advance understanding of the ocean.

Abstract Communicating the value of sustained ocean observing systems is urgent and necessary for their implementation, continuity, and expansion; and relies on effective dialogue among users at all levels to build support from policymakers and the public. This Ocean-Shot will build on the outcomes of OceanObs'19 and specifically work to realize the vision articulated in “The Challenge of Sustaining Ocean Observations” (Weller, 2019) and subsequent workshops hosted by the National Academies (2020). It will engage academia, industry, government, and nongovernmental organizations involved with global ocean observing and determine how to improve pathways to policymakers, stakeholders, and the public over the UN Ocean Decade. Key outcomes will include (1) broader understanding of how existing ocean observing science and policy areas intersect nationally and internationally, (2) identification of opportunities to build global support for ocean observing through cross-sector and international partnerships, and (3) determination of actions that the ocean observing community should take to develop a collective impact organization, the Ocean Partnership for Sustained Observations.
