New Microcurrents Discovered
What they show us about design
by Dr. Sarah Buckland-Reynolds
The ocean is earth’s great regulator, a system of currents that transport heat, nutrients, and carbon while sustaining fisheries and stabilizing climate. While much is known about the roles of currents, new technologies continue to uncover greater insights than previously known about their functions. One of the newest discoveries was published recently in Nature Geoscience.
An unprecedented view of ocean currents from geostationary satellites’ (Luc Lenain et al), Nature Geoscience (13 April 2026). Tapping into neural network methods, researchers Lenain et al (2026) discovered submesoscale currents (SMCs) through existing satellite imagery detecting temperature differences at the surface.
The AI-based detection of small-scale patterns at the surface of the ocean through existing geostationary satellites was termed as the Geostationary Ocean Flow (GOFLOW) framework. Using this GOFLOW framework, Lenain et al discovered that:
“Oceanic submesoscale currents dominate the vertical exchanges of heat, biological nutrients and carbon between the shallow and the deep ocean and strongly influence the lateral dispersion of biogeochemical tracers and pollutants.”
This discovery adds a new layer of complexity to the processes already known in the thermohaline circulation, as it reveals that the most critical exchanges in the ocean occur at scales previously invisible. In this article, we discuss further the mechanisms behind these observations and implications on intelligent design discourse.
Ocean Currents and Climate Regulation: What was Known and What is New?
Ocean currents function much like the arteries of the climate system. They transport heat from equatorial regions toward the poles, preventing extremes. Without them, equatorial zones would become uninhabitable deserts while polar regions would freeze beyond recovery.
While basin-scale currents such as the Gulf Stream are already known to provide these functions, the discovery of SMCs shows that fine eddies and filaments at the surface contribute greatly to this process. As was mentioned by the authors:
“These surface currents control the flux of mass, momentum and heat, interact with the atmospheric circulation and strongly modulate Earth’s weather and climate.”
SMCs operate at a much smaller spatial and temporal scale than basin-scale currents, with features that change hourly, redistributing heat and nutrients in ways that stabilize weather patterns.
Among the most profound nutrient exchanges is carbon cycling. The authors discovered that submesoscale turbulence drives vertical exchanges, sequestering carbon into the deep ocean and modulating atmospheric CO₂. Interestingly, the article notes that:
“…smaller scale currents that cannot be resolved by traditional altimetry capabilities dominate the vertical exchange of properties, such as heat, CO₂ and nutrients, between the ocean surface and its interior.”

Simultaneous to carbon sequestering, these SMCs also significantly support fisheries. Submesoscale convergence zones concentrate nutrients, sustaining plankton blooms, which support the foundation of marine food webs. In the words of the authors, the specific function of SMCs in fisheries are to “drive the formation of temperature fronts, alter ocean energetics and modify the vertical and horizontal transport of biogeochemical tracers and pollutants.” Without these currents, plankton would not bloom, and fish stocks would collapse.
These discoveries further confirm the precision of the processes involved at multiple scales simultaneously in earth’s oceanic systems. The multiscale regulation observed in SMCs requires significant engineering efficiency. In the case of carbon sequestration or even fisheries, if it depended on random turbulence, ecosystems would collapse. Instead, the systems exhibit coherence and purpose at multiple scales (and multiple simultaneous benefits), pointing to superior engineering.
Complexity Beyond Chance
Lenain et al.’s paper uncovered even more nuances of complexity in these SMCs that defied the expected processes that operate in larger-scale ocean currents, while still complementing the processes. In ocean science, the normal mode of currents is called geostrophic balance. This means the flow of water is mainly controlled by two forces: the pressure gradient (differences in sea surface height) pushing water, and the Coriolis effect (Earth’s rotation) deflecting it. When these forces balance, currents move smoothly along contours of sea surface height. Most large‑scale currents, like the Gulf Stream, are explained this way.
But the GOFLOW framework revealed something different: the SMCs followed ageostrophic flows, i.e., motions that do not follow this balance. Instead of smooth, balanced currents, scientists observed sharp twists and turns, with “pronounced skewness towards high strain, high positive vorticity and high negative divergence values… associated with motions of scales smaller than 30 km.” In simple terms, these smaller scale currents bend, stretch, and converge in ways that concentrate nutrients, stir the ocean vertically, and create fine‑scale turbulence.
What is profound is that even though the processes and patterns differ at large vs. the SMC scales, the differences in processes complement each other in their functions to drive nutrient convergence, vertical mixing, and ecosystem resilience. Without the difference in processes, the ocean would not recycle nutrients efficiently or sustain fisheries.
Implications for Gradualism
What implications would this have on a gradualistic view of ocean current origins? Evolutionary geology frames currents as emergent features shaped by tectonics and random turbulence. Yet this discovery undermines such narratives.
Emerging questions would include: Could a half‑formed or incomplete current system regulate climate or support life? Based on the profound functions that these currents provide, it appears that these currents had to function as a fully integrated system from the beginning for Earth to be habitable. This points not to gradual chance, but to design embedded in the ocean’s circulation system.
The Oceans Declare Superior Engineering in Earth’s Systems
The discovery of submesoscale currents forms yet another powerful example of the finely tuned engineering of Earth’s systems, working in tandem with larger scale systems to sustain climate, fisheries, and habitability. Such integrated systems point to foresight and purpose. For climate science and oceanography, this discovery opens new horizons for further exploration of intelligent design in nature. Profound questions for potential future research may include SMCs’ interaction with other systems such as earth’s atmosphere, changes with human intervention (e.g., pollutions), as these may point to new frontiers of discovery that are relevant to intelligent design.
As further research continues, these findings certainly continue to point to the glory of God and the intricate care He places in designing multilevel processes in nature. The coherence, precision, and superior engineering of ocean currents certainly declare the glory of God.
