TL;DR
Google says it and CSIRO used kelp-specific AI tools to analyze DNA from 600 wild giant kelp specimens collected at 40 Tasmanian coastal sites. The work aims to help researchers select native kelp for selective breeding, but the specimen analysis has not yet been documented in a paper or public dataset, and whether bred kelp can withstand warmer seas remains unknown.
Google says CSIRO researchers used a version of its DeepVariant AI tool, retrained for kelp DNA, to analyze 600 wild giant kelp specimens from 40 sites along Tasmania’s coast. The analysis is intended to help scientists select native plants for selective breeding as they seek to restore kelp forests that have fallen to about 5% of historic levels, according to Google; whether bred kelp can survive warmer conditions in the sea has not yet been tested.
The project’s genome work provides a reference for comparing the kelp samples. In a study published in BMC Genomics in June 2026, researchers including CSIRO scientists and a Google researcher reported two Australian giant kelp reference genomes, based on plants from Victoria and Tasmania. The study says the Australian genomes differ from one another by 0.2%, while each differs from the Californian reference genome by 1.5%. The researchers said that relying only on the Californian genome could complicate analysis of Southern Hemisphere kelp.
Google’s November 12 announcement says its open-source tools helped researchers assemble the Australian reference genomes and that a kelp-trained version of DeepVariant was then used to analyze the 600 wild specimens. Google also says DeepConsensus and DeepPolisher helped correct errors in raw genetic reads. Those tools process and compare genetic information; they do not directly measure heat tolerance. The source of information about the 600-sample analysis and its reported finding of genetic isolation among remaining Tasmanian patches is currently Google’s announcement and accompanying video, rather than a published paper or dataset.
CSIRO and its partners plan to cross genetically distinct native survivors in laboratory breeding work and plant young kelp on reefs. The source describes this as selective breeding, not genetic modification. Lab tests can assess traits such as heat response, but the practical test is whether the resulting kelp persists through warm summers in its natural environment.

Selecting Kelp for Warmer Seas
The research targets a major obstacle to restoring Tasmania’s giant kelp: scientists need to know which surviving plants carry useful genetic differences before they can choose candidates for breeding. A reference genome from Australian kelp gives researchers a closer local comparison than the previously available Californian genome, while DNA analysis across many wild samples may help identify how the remaining populations are related.
The stakes extend beyond the seaweed itself. Giant kelp forms underwater forests that provide habitat for marine life, including fish, octopuses and sea stars. CSIRO has described the decline as a loss of an ecosystem, and the source material says the forest community is listed as endangered. If selected kelp can survive local conditions, breeding could support restoration efforts; the AI analysis alone does not show that restoration will succeed or address the environmental pressures driving the decline.

From Genome Maps to Reef Trials
Giant kelp, Macrocystis pyrifera, grows in cold, shallow seas. Around Tasmania, plants can reach about 30 metres, according to the source material. CSIRO attributes the local decline to warmer, nutrient-poor water and sea urchins associated with the East Australian Current moving farther south. The Tasman Sea has warmed rapidly, while shallow Tasmanian waters leave the kelp with limited room to shift its range southward.
The broader collaboration was announced in February 2024 by Google Australia, CSIRO, the University of Tasmania’s Institute for Marine and Antarctic Studies, The Nature Conservancy, the Great Southern Reef Foundation and the Kelp Forest Alliance. It included a mapping strand, using satellite imagery and Google tools to identify remaining kelp, as well as the genomics work described in the latest announcement. The June 2026 genome paper is peer-reviewed; the later account of the 600 specimens and their genetic isolation is not yet supported by a paper or dataset cited in the source material.

The Field Test Still Lies Ahead
The key near-term evidence gap is the 600-specimen analysis. Google says the remaining Tasmanian patches are genetically isolated, but the source material identifies no published paper or public dataset documenting that result. The methods, detailed findings and independent scrutiny of this part of the project therefore remain unclear.
It is also not yet known which genetic traits the researchers will use to select breeding candidates, how many plants will be crossed or where and when young kelp will be planted. Most importantly, there is no reported result showing that selectively bred kelp can withstand warmer summers, persist on reefs or rebuild a forest. The project does not remove the warming, nutrient changes or sea urchin pressures cited as drivers of decline.
Breeding and Reef Planting
The next planned stage is for scientists to cross distinct native kelp survivors in the laboratory, then plant young kelp on reefs. The source material does not give a schedule for those trials or specify when results will be available. A paper or released dataset on the 600-sample analysis would also allow researchers outside the announcement to assess the reported genetic patterns.
Future updates will need to distinguish laboratory measures of heat response from survival in the ocean. The decisive evidence will be whether the bred kelp persists through warm seasons under reef conditions, and whether any surviving plants contribute to forest recovery.
Key Questions
What did Google and CSIRO use AI for?
Google says a kelp-trained version of DeepVariant analyzed DNA from 600 wild giant kelp specimens. Other Google tools helped with genome assembly and correction of errors in raw genetic reads. The tools support genetic analysis; they do not directly test whether kelp can tolerate heat.
Has the AI analysis of all 600 samples been peer-reviewed?
Not according to the source material. The two Australian reference genomes are reported in a peer-reviewed June 2026 paper in BMC Genomics. The 600-sample analysis and reported genetic isolation are described in Google’s November announcement, with no paper or dataset identified there.
Does the project genetically modify kelp?
No. The planned approach is described as selective breeding: crossing distinct native survivors in a laboratory and planting young kelp on reefs. The source material says it is not genetic modification.
Will the bred kelp survive warmer summers?
That remains unknown. Laboratory tests can examine traits such as heat response, but the field test has not yet happened. Researchers will need to see whether planted kelp persists through warm conditions in the sea.
