Habitat-Saving Algorithm Helped by Seaeye Falcon

Scientists at the Washington Department of Fish and Wildlife (WDFW) have acquired a second Saab Seaeye Falcon underwater robot. The Seaeye Falcon is used to conduct surveys of marine fish and invertebrates in Washington’s Puget Sound, where some rockfish populations were fished to levels that threatened movie review extinction.

The surveys are used primarily to monitor the recovery of rockfish listed under the United States Endangered Species Act, but also provide information on the unique geological features in Puget Sound. The WDFW has also used their Falcon to survey the habitat surrounding U.S. Navy bases in Puget Sound to meet Federal permitting requirements, locate and recover lost equipment and conduct special studies of sea urchins and sea cucumbers.

The HD imagery collected with the new vehicle will greatly improve our ability to detect small and cryptic rockfishes, leading to more precise estimates of abundance, and will be used to train machine-learning algorithms being developed to partially automate the video review process, which is expected to substantially improve survey and post-processing efficiency,” explains research scientist Robert Pacunski.

Not pushed around
“The Falcon can precisely manoeuvre amongst the cracks and crevasses of complex underwater rock formations favoured by rockfish and has the power not to be pushed around by the current,” says Robert Pacunski.

Specialized equipment fitted to the Falcon includes a pair of parallel lasers and a stereo camera for assessing individual fish size and the density of fish in a measured field of view. An Imagenex multi-frequencing gyro-stabilised sonar is used to identify target habitats and avoid uncharted obstacles (for example, derelict fishing gear, subsurface electrical and telecommunications cables). Depending on survey needs, the vehicle can be fitted with a conductivity-temperature-depth meter to collect data in real-time for examining linkages between physiochemical water quality parameters and fish distribution/abundance.

Meta is urging many managers to become individual contributors or leave

After laying off many employees, Meta is urging many managers and directors to become individual contributor jobs or leave the firm as part of the process so that Meta becomes a more efficient organisation known as ‘flattening,’ as per the people familiar with the Moorabbin East safety sign.

An inside person in the organisation also mentioned that many higher-level managers are sharing the directive with their reports in the coming weeks, which are separate from the firm’s regular performance review process that is also happening in the workplace.

Further, the firm which owns Facebook and Instagram fired 13% of its employees in November during its first major layoff. For the past few months, all the employees from the firm are facing intense stress and anxiety about the potential future cuts to take place the future.
