| Seascape Aquatech, Inc., based at the eastern tip of Long Island, New York is developing a comprehensive set of robotic and automation systems for oyster aquaculture. These systems will automate every facet of oyster shellfish aquaculture from juvenile rearage through market preparation of the harvested oysters. One of the more prominent aspects of our system is the development and use of a small fleet of autonomous surface vehicles; i.e. robotic boats. These are used to service and monitor thousands of floating cages along anchored lines. The company presently operates an oyster farm in East Hampton NY, and is actively negotiating acquisition of several other shellfish farms throughout North America and Europe. Each acquisition will be outfitted with Seascape's proprietary technology, to significantly improve quality and cost efficiency of yields.
In short order, the company intends to expand the scope of its robotic aquafarming systems to include kelp as well as other shellfish, notably scallops, mussels, clams, and cockles -- specifically with an eye toward multitrophic farming at scale. |

| The method for labor-saving cultivation of seaweed containing high density glucose.　　　　
Conventional seaweed cultivation is labor-intensive and expensive.
Seaweed: Chaetomorpha contains high density glucose that is material of ethanol.
The floatable block is foaming glass made of waste glass and that is safe & cheap.
I demonstrated that Chaetomorpha can be adhered on the floatable block.
The process of cultivation with floatable block is below.
・Start of cultivation : Scatter floatable blocks attached premature seaweed.
・Harvest: Floatable blocks attached grown seaweed can be collected by simple colander.
・Separate seaweed from floatable block: Potato auto-peeling machine is expected to be available.
As all process can be automatically, the culture cost become low.
And as seaweed is supplied enough sunlight and oxygen, it will continue to grow even after the seaweed at bottom is dead.
Japanese academia demonstrated ethanol can be made from Chaetomorpha.
When cultivating seaweed in poor nutrient waters, it is necessary to supply nutrients.
A floatable block impregnated aqueous nutrients solution and coated with biodegradable plastic film and so on can supply nutrients during a few months.
Biofuel production process needs much heat especially for ethanol distillation and residue drying. As thermal power plant exhaust huge heat loss, it could be available for biofuel production process.
EPR (Energy profit ratio:Produced energy / Consumed Energy) is estimated to be approximately 1.5.
In the future, the material of floatable block is expected be supplied from coal / incinerated ash by high temperature melting furnace that realize to separate heavy metal / rare earth almost completely and high grade detoxified white powder.
As deep ocean water contains high density of nutrients, which can be used to cultivate seaweed.
It is known that seaweed and cyanobacteria that have the ability to fix nitrogen coexist symbiotically in nature.
It may be possible to eliminate the need for nitrogen fertilizer by culturing seaweed and cyanobacteria simultaneously on the floatable block.
Seaweed collect nutrients from sea.
As drain from ethanol product process contains high density nutrients, they can be available for fertilizer. |

| Our research has focused on modeling the effects of offshore wind farms on local oceanography and marine life (Wang et al., 2024; Santana et al., 2022). We also studied the synergy between offshore wind farms and aquaculture. We're also at the forefront of studying wind turbine behavior under various environmental conditions, contributing to the design of more resilient and efficient wind energy systems (Golparvar et al., 2021).
In the realm of hydrokinetic energy, we're developing environmentally friendly devices that harness the kinetic energy of water flow. Our work includes designing reconfigurable hydrokinetic arrays (Bilgen et al., 2022) and creating new frameworks for assessing fish collision risks and flow alterations caused by turbine deployment (Asok and Wang, 2024). We've also made significant contributions to tidal and wave energy research, assessing energy distribution patterns and advancing the design of wave energy converters (Deng et al., 2019; Shadmani et al., 2023).
An exciting area of our research explores the synergy between offshore wind energy and aquaculture. By studying the hydrodynamic impacts of aquaculture gears in conjunction with marine renewable energy installations, we're paving the way for more sustainable and efficient use of ocean resources (Shao et al., 2021; Yang et al., 2022). |

| GreenWave's mission is to replicate and scale regenerative ocean farms (kelp farms) to create jobs and protect the plant. We deliver programming to a global audience through our online hub (hub.greenwave.org; exceeding 7000 registered users), and lead hands-on training for kelp farmers in the U.S. and Canada. Approximately 70 (of approximately 230) kelp farmers across coasts in North America track and report kelp growth and yield data in GreenWave's My Kelp app. In addition to training farmers, we replicate and scale key infrastructure that is vital to the success of the industry (including kelp nurseries and post-harvest processing and stabilization equipment) and support value chain coordination between seed producers, farmers, buyers, and processors through our high-touch programming and online app, Seaweed Source.
We are also ocean farmers. GreenWave owns and operates two kelp farms in near coastal waters in Southern New England (SNE), where we grow sugar kelp (Saccharina latissima). We also established leases for farm sites in Humboldt Bay, California and worked closely with project partners to cultivate bull kelp (Nereocystis lutkeana). We run a production-oriented seed bank for kelp gametophytes in SNE and have gained experience producing high-quality gametophytes for multiple kelp species. We provide gametophytes to nurseries from New York to Maine, and produce seed string with gametophytes for farmers throughout the region.
More recently, GreenWave partnered with AgriSea, a New Zealand-based biostimulant company, to co-developed a kelp-based biostimulant using raw, wet sugar kelp and ambient temperature stabilization methods. GreenWave established an agreement with AgriSea to manufacture biostimulants in North American under the AgriSea brand, and open up new market opportunities for North American kelp farmers. GreenWave sources kelp from ocean farmers in the Northeast Atlantic region, manufactures the biostimulant in Connecticut, and sells product to land-based farmers throughout the U.S. |

| Artimus Robotics has developed a new type of soft transducer, called HASEL (pronounced 'hey-zul'). Operating on an electrohydraulic mechanism, these transducers can act as actuators for bio-inspired robotics and generators for ocean wave/tidal energy harvesting. Currently, we are interested in utilizing HASELs in next-generation underwater robotics that can support burgeoning applications like seaweed aquaculture. As actuators, HASELs have been tested to pressures at full ocean depth without loss of performance. They also have negligible ‘self-noise’ and minimal magnetic signature, which limits interference with other sensor technologies within proximity. These actuators can be used for bioinspired propulsion of underwater vehicles, as well as robotic end-effectors for dexterous grasping and manipulation. With these features, we believe our technology can enable new autonomous robotic platforms that are targeted at the second objective of HAECHO - creating offshore scale through hardware and control systems that support depth cycling.
Admittedly, our team has limited background and knowledge in seaweed aquaculture. We would like to partner with experts within this market who understand the state-of-the-art and key challenges regarding autonomation and robotics in order to inform our strategy and ensure long-term success. We thank you for your time in advance. |

| Seafields is a science-led, UK-based startup aiming to use aquafarming of the macroalgae Sargassum to build a scaled, offshore seaweed industry that can supply algae biomass at gigaton scale for biostimulant, plastic or energy production or carbon dioxide removal.
We have a prototype farm and are fundraising to install a demonstration size farm in a near-shore environment in the Caribbean. Both these farms are well suited to test new sensors and models for the development of smart aquafarms. We are very interested in working with universities and research labs to develop autonomous ways to measure biomass growth and other aspects of our aquafarm.
For our offshore farms, we plan to install them in the gyres and use stommel principle upwelling pipes to bring nutrients up from a depth of 400 m. We have modelled these pipes and are looking to construct a scaled model to test the principle.
Our partner company Carbonwave has developed a Sargassum biostimulant that has been tested by large offtake firms on the market. Their method of producing the biostimulant partially dewaters the Sargassum by extracting ~60% of the weight of the algae as water.
The potential of Seafields’ methodology has been recognised by a number of prestigious accolades, including selection as a runner up team (Top 29 teams) in the XPRIZE Carbon Removal, and receiving Startup of the Year at the SeedLegals Awards 2024. |
