Technology Development

At present, AVL is incubating two companies: one focused on engineered ocean upwelling (pelagic aquaculture), the other on mitigating thermal stress in salmon rivers (thermal refugia). Below are links to the upwelling tech and thermal refugia white-papers, along with some brief information about future projects.


A Medical Device for the Ocean

Increasing primary productivity through artificial upwelling

Look in the ocean anywhere upwelling occurs and you will find life. Upwelling occurs in just one percent of the ocean’s area but accounts for nearly 50% of global fisheries production, sustaining the richest fishing grounds in the world. Nutrients from upwelling account for most of the primary biological productivity of the world’s oceans. Absent upwelling, the ocean will be a literal “desert” as measured by fish per square mile.

Relieving Thermal Stress in Pacific Salmon Rivers

Thermal refugia through technology

Over the last 50 years, multiple factors have contributed to the current Pacific salmon crisis—things like industrial dams, agriculture irrigation water diversion, overfishing, and the effects of climate change.

 As climate change intensifies, river temperatures are rising while water volume levels simultaneously decline, and the combined effect creates considerable stress on salmon at the egg fertilization stage, fry stage and the returning adult spawning stage. Currently, the negative effects of lower water levels and higher water temperatures are most acute in California and Oregon. But they’re already being felt in the north.


Future Projects

Our work groups are exploring future projects in the following areas:

  • Desalination tech: Pipeline and mobile

  • Re-oxygenation: Mixing, compressed O2 input, hydrogen production byproduct

  • Reaper series: HABs, purple urchin, sea lice, northern pike, invasive species

  • Filtration and extraction: Pollution, toxins, plastic debris, microplastics

  • Augmented nature: Free range aquaculture

  • Asset repurposing: Oil rigs and tankers, seabed pipelines, cargo ships

Due to the confidential nature of technology development, proprietary details of engineering designs are not made public.

Primary areas of interest

AVL’s interest is centered on exploring technological approaches to mitigating ocean conditions caused or exacerbated by human activity, with a particular focus on supporting existing natural processes and ecosystems in the following arenas:

  • Pollution filtration through static, active, and biologic methods

  • Re-oxygenation of hypoxic conditions

  • Thermal attenuation of habitat or species such as thermal refugia for salmon in heat stressed rivers or for coral to reduce bleaching

  • Carbon sequestration through supporting and/or augmenting natural ocean processes

  • Biologic life support and habitat development

  • Reducing harmful algae blooms

  • Mitigating the effects of ocean acidification or rebalancing pH

  • Mitigating pollution, plastics, and excessive waste introduced into rivers and estuaries through industrial or agricultural runoff

  • Exploring ways tidal or ocean current dynamics can be harnessed to enhance the effectiveness of technological solutions

  • Examining how geologically controlled bodies of water respond differently to biologic enhancements compared to open-ocean areas

  • Improving conservation in marine biodiversity hotspots

  • Exploring energy capture and usage in situ, with materials and manufacturing methodologies suited for harsh weather and corrosion
