MCS want you to report jellyfish and turtles on our shores 

Published

on

The Marine Conservation Society’s Wildlife Sightings programme focusses on two key marine animals: jellyfish and, as a result, turtles. Both are vital in supporting ocean biodiversity and are indicators of changes in our ocean, like warming waters.

Since 2003, when the Marine Conservation Society’s Wildlife Sightings programme began, the charity has had 18,580 sightings reported – 18,357 of jellyfish and 223 of turtles.

Jellyfish can be spotted year-round in UK and Irish seas, but larger blooms are more likely to appear in spring, lasting through until autumn. Jellyfish sighting records from 2022 show that the most frequently reported jellyfish species were the moon jellyfish, accounting for 22% of sightings, followed by the barrel jellyfish at 21%. The compass jellyfish and lion’s mane jellyfish were also commonly sighted, comprising 19% and 15% of the reports, respectively. These findings provide valuable insights into the prevalence of jellyfish species in UK and Irish seas.

Sightings of jellyfish and turtles should be reported online when spotted by beach or sea goers to support ongoing research. Identification and reporting take just a few minutes using the charity’s easy identification cards and online form.

During spring and summer, jellyfish arrive in the UK and Ireland’s warming waters to feed, feasting on plankton blooms and the array of eggs and larvae of fish, crustaceans, starfish and molluscs which are common at this time of year.

With healthy fish stocks and rich biodiversity, jellyfish quickly become part of an effective food chain. Many species, from tuna to turtles, will feed on jellyfish of various sizes. Supported by a rich and diverse ocean ecosystem, jellyfish link the microscopic world of plankton to larger marine animals and the ocean around them.

The charity’s data shows an increasing trend in some species being spotted on our shores over the last 20 years, such as Portuguese man o’War. Research has suggested that an increase in some jellyfish numbers around UK could be related to climate change, however, currently there isn’t enough evidence to make this link. The Marine Conservation Society’s Wildlife Sightings programme aims to collect long term data which can be used as a reference to study the reality of jellyfish trends in UK waters.

Jellyfish are especially appealing for marine turtles to eat. Six of the world’s seven marine turtle species have been spotted in UK seas, some of which arrive due to large abundances of jellyfish in spring and summer. The charity also reported an increase in marine turtles earlier this year, when strong currents and winds potentially blew turtles off their usual course and into our seas. The charity has a Turtle Code information sheet which shows what to do with a beached turtle.

The largest sea turtle, and the most common in UK and Irish seas, is the leatherback, which has a ‘vulnerable’ conservation status. Reporting sightings of these incredible creatures will support the Marine Conservation Society and others in understanding their movements, potential threats and how better to protect them.

The charity’s volunteers submitted 223 turtle sightings since 2003, which feeds into a national database which recorded nearly 1,000 (946) turtle sightings over the same period. The research is used to inform policies and introduce conservation strategies to better protect our ocean and its inhabitants.

Dr Peter Richardson, Head of Ocean Recovery at the Marine Conservation Society, said:“Without your data, we wouldn’t be able to prove that our ocean is facing problems, or push for solutions that are backed by science. Data on jellyfish and turtles helps us build a picture of life in UK and Irish seas and track any changes that may occur because of things like climate change.  

“Since 2003, when our Wildlife Sightings programme began, you’ve reported over 18,000 sightings of jellyfish and turtles. We want to reach 20,000 sightings to mark our 20th year of tracking these species. Every contribution to our database is crucial in learning about our seas and helps us fight to protect them.”

The Marine Conservation Society uses wildlife sightings by citizen scientists to:

  • Discover how jellyfish and turtle populations are changing around the UK – specifically when and where they are occurring each year
  • Investigate trends in turtle sightings to find out more about how they use our waters
  • Explore whether jellyfish distribution can tell us more about where leatherback turtle feeding grounds may be

Heading out on the water this Summer? Watch for manatees

Published

on

manatee

As National Safe Boating Week approaches, Save the Manatee® Club is urging boaters, and anyone that enjoys Florida’s waterways, to respect and protect the defenseless manatees that inhabit our shared waterways. From May 18 to 24, leading up to Memorial Day Weekend, the campaign aims to raise awareness about recreational boating safety and the importance of safeguarding imperiled manatees during the summer boating season. This week also emphasizes the importance of encouraging boaters to enroll in a boating safety course.

Manatees are semi-migratory marine mammals that are commonly found in shallow estuaries, bays, rivers, canals, and coastal areas throughout Florida and neighboring states. With some manatees venturing as far west as Texas and as far north as Massachusetts, collisions between these gentle giants and watercraft have become distressingly frequent. Boat propellers and high-speed collisions pose significant threats to manatees, often resulting in severe injuries or even death.

Save the Manatee Club is calling on all water enthusiasts to follow essential manatee safety tips to ensure the well-being of the imperiled manatee:

  • Obey Speed Zone Signs: Familiarize yourself with and adhere to posted speed limits to prevent collisions with manatees.
  • Reduce Glare with Polarized Sunglasses: Wear polarized sunglasses to enhance visibility and spot manatees below the water’s surface.
  • Recognize Manatee Signs: Learn to identify signs of manatees in the area, such as swirls or flat spots on the water caused by their movements.
  • Respect Manatee Sanctuaries: Keep a safe distance from posted manatee sanctuaries and avoid pursuing or harassing these marine mammals, as it is illegal and can disrupt their natural behaviors.
  • Report Distressed Manatees: In Florida, promptly report distressed, injured, tagged, or orphaned manatees to the Florida Fish and Wildlife Conservation Commission (FWC) at 1-888-404-FWCC (3922). Outside of Florida, report sightings to the appropriate state agency or rescue organization. A list of agencies to contact is available at savethemanatee.org/report.
  • Protect Seagrass Beds: Avoid boating over seagrass beds and shallow areas where manatees may be feeding. Stick to deep water channels while remaining vigilant, as manatees also utilize these channels during their travels.
  • Dispose of Fishing Line Responsibly: Anglers should properly dispose of or recycle used fishing line to prevent entanglement hazards for manatees.

“Each year, National Safe Boating Week provides an excellent reminder for all of us to be aware that we share our waterways with vulnerable manatees,” emphasized Patrick Rose, Aquatic Biologist and Executive Director of Save the Manatee Club. “With the recent Unusual Mortality Event on Florida’s East Coast claiming an alarming number of manatees’ lives, it is more crucial than ever to prevent preventable deaths caused by watercraft collisions. By following manatee-safe boating guidelines, such as obeying speed zones and remaining vigilant for manatees, everyone on the water can contribute to the protection of these gentle giants.”

Save the Manatee Club offers a range of free materials to help safeguard manatees and raise awareness about manatee-safe boating practices. Shoreline property owners and park or marina managers can order aluminum dock signs to alert others about the presence of manatees in their areas. Boaters and paddlers can request packets containing a safety tips card, a waterproof boat banner, and a decal to display on their vessels, providing the number to report manatees in distress. To view and request these materials, visit savethemanatee.org/resources. Save the Manatee Club will also be hosting a live webinar for National Safe Boating Week on Tuesday, May 21st at 6pm EST. To register, visit savethemanatee.org/register.

The Ocean Cleanup Breaks 10,000,000 KG Barrier

Published

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.
