Canadian Dive Computer manufacturer Shearwater Research have announced the release of a firmware update for the Petrel and the Petrel 2 in their latest newsletter.

Listing of changes in Petrel Firmware v33

These changes apply to both the Petrel and Petrel 2 unless otherwise noted.

NEW FEATURE: After changing the battery, the current deco tissue loading is shown on the Tissues Restored screen.

NEW FEATURE: On the Tissues Restored screen, a shortcut to reset the tissues is given. If Reset is chosen, a prompt will be displayed to confirm.

Do NOT reset tissues between repetitive dives, as inert gas loading will be lost.

Battery-Changed

The tissues bar graph is now shown on the Tissues Restored screen

CHANGE (Petrel 2 only): Compass mark heading menu moved to reduce button presses. Also, the compass can now be viewed while marking. Operation: when viewing compass a left button press brings up an “Exit Mark” menu. Right press marks compass, Left press exits to main screen. Previously had to navigate to regular menus to mark the compass.

The mark heading command now requires less button presses

IMPROVEMENT (Petrel 2 only):  When a heading is marked, the display now shows the offset angle between the current heading and the marked heading. This is useful for navigating patterns. For example, a box pattern requires turns at 90° intervals, while a triangle pattern requires turns at 120° intervals.

The offset between current and marked heading is now shown (in this example 16°)

The offset between current and marked heading is now shown (in this example 16°)

IMPROVEMENT (Petrel 2 only): Compass display improvement. The ‘N’, ‘E’, ‘S’, and ‘W’ characters changed to a larger font.

NEW FEATURE: New “Cave” brightness setting. This is even dimmer than Low brightness, and is suitable for very dark environments like caves or night diving.

Cave brightness is very dim and thus best suited for dark environments like caves.

Cave brightness is very dim and thus best suited for dark environments like caves.

BUG FIX: Fixed problem where gas usage for bottom time segment in dive planner was too low, due to the ascent rate (33 fpm) being used to calculate descent (60 fpm). This problem only affected gas usage calculations and not the decompression schedules.

NEW FEATURE: As a secondary backup to the super-capacitor the deco tissues and clock into permanent memory every 16 seconds when on (every 5 minutes when off). These backups will be used once the super-capacitor is drained.

On the “Bus Devices” page, choose “View” to see more info and setting

NEW FEATURE (DiveCAN Models Only):  Added support for changing settings on peripheral boards.

For example, on the SOLO board (solenoid and oxygen controller) the Solenoid Speed setting can be adjusted. Go to “Bus Devices” page on Petrel to access peripheral boards. Settings viewed here are stored on the peripheral device.

Firmware updates on peripheral boards may be required before settings can be adjusted.

If settings are available, they can be changed here. These settings are stored on the peripheral device.

The Ocean Cleanup Breaks 10,000,000 KG Barrier

Published

on

ocean cleanup

The Ocean Cleanup, the global non-profit project, has removed a verified all-time total of ten million kilograms (22 million lbs.) of trash from oceans and rivers around the world – approximately the same weight as the Eiffel Tower.

To complete its mission of ridding the oceans of plastic, The Ocean Cleanup uses a dual strategy: cleaning up the Great Pacific Garbage Patch (GPGP) to remove the plastic already afloat in the oceans, while stopping the flow of plastic from the world’s most polluting rivers.

Through cleaning operations in the GPGP and in rivers in eight countries, the cumulative total of trash removed has now surpassed ten million kilograms. This milestone demonstrates the acceleration of The Ocean Cleanup’s impact, while underlining the astonishing scale of the plastic pollution problem and the need for continued support and action.

While encouraging for the mission, this milestone is only a staging point: millions more tons of plastic still pollute our oceans and The Ocean Cleanup intends to continue learning, improving and innovating to solve this global catastrophe.

This announcement comes as governments from around the world meet to continue negotiations to develop a new legally binding instrument to end plastic pollution at INC4 in Ottawa, Canada. Representatives of The Ocean Cleanup will be in attendance and the organization will be urging decision-makers to collaborate towards a comprehensive and ambitious global treaty which addresses plastic at all stages of its life cycle and in all marine environments worldwide, including in areas beyond national jurisdiction.

It is encouraging to see that the need for remediation is reflected in the various options for potential treaty provisions. It is essential that the final treaty contains clear targets for the remediation of legacy plastic pollution, and reduction of riverine plastic emissions.

Tackling plastic pollution requires innovative and impactful solutions. The treaty should therefore incentivize the innovation ecosystem by fostering innovations that make maximal use of data, technology and scientific knowledge – such as those designed and deployed by The Ocean Cleanup.

‘After many tough years of trial and error, it’s amazing to see our work is starting to pay off – and I am proud of the team who has brought us to this point.’ said Boyan Slat, Founder and CEO of The Ocean Cleanup. ‘While we still have a long way to go, our recent successes fill us with renewed confidence that the oceans can be cleaned.’

The Ocean Cleanup was founded in 2013 and captured its first plastic in 2019, with the first confirmed catch in the GPGP coming soon after the deployment of Interceptor 001 in Jakarta, Indonesia. After surpassing one million kilograms of trash removed in early 2022, the non-profit project has since progressed to the third iteration of its GPGP cleaning solution, known as System 03, and a network of Interceptors currently covering rivers in eight countries, with more deployments set for 2024.

About The Ocean Cleanup

The Ocean Cleanup is an international non-profit organization that develops and scales technologies to rid the world’s oceans of plastic. They aim to achieve this goal through a dual strategy: stemming the inflow via rivers and cleaning up the legacy plastic that has already accumulated in the ocean. For the latter, The Ocean Cleanup develops large-scale systems to efficiently concentrate the plastic for periodic removal. This plastic is tracked and traced through DNV’s chain of custody model to certify claims of origin when recycling it into new products. To curb the tide via rivers, The Ocean Cleanup has developed Interceptor™ solutions to halt and extract riverine plastic before it reaches the ocean. Founded in 2013 by Boyan Slat, The Ocean Cleanup now employs a broadly multi-disciplined team of approximately 140. The foundation is headquartered in Rotterdam, the Netherlands.
