Antarctic marine life recovery following the dinosaurs’ extinction

A new study shows how marine life around Antarctica returned after the extinction event that wiped out the dinosaurs. A team led by British Antarctic Survey studied just under 3000 marine fossils collected from Antarctica to understand how life on the sea floor recovered after the Cretaceous-Paleogene (K-Pg) mass extinction 66 million years ago. They reveal it took one million years for the marine ecosystem to return to pre-extinction levels. The results are published today (19 June 2019) in the journal Palaeontology.

The K-Pg extinction wiped out around 60% of the marine species around Antarctica, and 75% of species around the world. Victims of the extinction included the dinosaurs and the ammonites. It was caused by the impact of a 10 km asteroid on the Yucatán Peninsula, Mexico, and occurred during a time period when the Earth was experiencing environmental instability from a major volcanic episode. Rapid climate change, global darkness, and the collapse of food chains affected life all over the globe.

The K-Pg extinction fundamentally changed the evolutionary history of life on Earth. Most groups of animals that dominate modern ecosystems today, such as mammals, can trace the roots of their current success back to the aftermath of this extinction event.

A team of scientists from British Antarctic Survey, the University of New Mexico and the Geological Survey of Denmark & Greenland show that in Antarctica, for over 320,000 years after the extinction, only burrowing clams and snails dominated the Antarctic sea floor environment. It then took up to one million years for the number of species to recover to pre-extinction levels.

Author Dr Rowan Whittle, a palaeontologist at British Antarctic Survey says:

“This study gives us further evidence of how rapid environmental change can affect the evolution of life. Our results show a clear link in the timing of animal recovery and the recovery of Earth systems.”

Author Dr James Witts, a palaeontologist at University of New Mexico says:

“Our discovery shows the effects of the K-Pg extinction were truly global, and that even Antarctic ecosystems, where animals were adapted to environmental changes at high latitudes like seasonal changes in light and food supply, were affected for hundreds of thousands of years after the extinction event.”

NATURE AND TIMING OF BIOTIC RECOVERY IN ANTARCTIC BENTHIC MARINE ECOSYSTEMS FOLLOWING THE CRETACEOUS-PALEOGENE (K–PG) MASS EXTINCTION by Rowan J. Whittle, James D. Witts, Vanessa C. Bowman, J.

What Our Members Say

We are a small family owned and run business that the introduction of new measures by BF would have caused severe financial hardship. I was recommended to ask BBGA for advice which they instantly gave even though we were not members. They attended various meetings by my side, took the situation to a higher level within the Government department and helped me achieve a satisfactory outcome. I wasn’t pressured to become a member but what became apparent was their genuine desire to help resolve aviation issues for the better of the community. This association covers almost every aspect of the industry, has representation on the majority of decision making panels and achieves results by either diluting possible harmful legislation or stopping it altogether. Its members receive updates in real time often leaving other associations to ‘cut and paste’ BBGA releases some time later.

Inflite The Jet Centre Ltd.Penny Stephens, Director

BBGA is the main business and general aviation industry Association in the UK. It represents a wide range of services and operators. It’s contribution to fairly represent our interests with the regulators and government departments as well as other associations is absolutely essential. The various BBGA events throughout the year are a great opportunity for everyone to network and discuss the current industry affairs and issues BBGA’s ability to bring together all sectors of UK general and business aviation gives us enviable networking access. Nobody has the ear of the regulator like BBGA and that’s two-way thing; BBGA is not just able to elicit answers from EASA, the CAA and DfT, its advice and recommendations are sought both nationally and supra-nationally too. That makes membership a vital way to influence upcoming policy.

Luxaviation United Kingdom, London Executive Aviation LtdGeorge Galanopoulos, CEO & Managing Director

The BBGA is the key trade body for UK business aviation, helping us keep up-to-date with developments and in contact with the wider UK bizav community. Everyone with any interest in UK business aviation should be a member

Clyde & CoMark Bisset Partner,

From first contact, to membership, to attending the 2021 Virtual Conference, I received a warm welcome for which I am extremely grateful. The mix of technical and strategic content re-enforced the decision to attend and was the right one at the right time for our business."

Paul Cremer

My name is Paul Cremer, and this marks my 42nd year working within the business and general aviation industry. Over this time, I’ve had the privilege of overseeing a diverse array of sector activities, ranging from aircraft charter and management to air ambulance services, ground operations, air traffic control, airport management, technology implementation, and the outsourcing services I currently manage.

In my role focused on delivering advisory, technology, and outsourcing services to aviation customers, I handle a wide spectrum of responsibilities. This includes overseeing International Trip Support, Operations Control Centre Services (OCC), Continuing Airworthiness Management Service (CAMO), Airworthiness Reviews, ARC Services, Aircraft Delivery and Re-delivery Support Services, Maintenance Coordination Services including AOG, Tech Ops (Maintenance Control Centre), and managing myairops software products. As the Head of Aviation Delivery, I lead the customer-facing delivery of Technology & Outsourcing products and services for the market, drawing upon a wealth of knowledge, expertise, and industry connections within Gama Aviation’s Technology and Outsourcing Strategic Business Unit.

My journey into Business and General Aviation began during my teenage years while still in school. I was fortunate enough to be welcomed into the industry, starting at a flying club, and later working at the Air Traffic Services Unit at Blackbushe Airport. There, I maintained the ATC Movement Logs in the Control Tower during weekends, solidifying my passion for aviation. Upon completing my schooling, I seized opportunities at Fairoaks Airport, where I began as Ground Crew while pursuing my Aerodrome Flight Information Service Officer’s license. Advancements in my career led me to the role of Air Traffic Services Manager.

Since joining Gama Aviation in 1996, I’ve held various positions, including Operations Manager (Post Holder), Operations & Commercial Manager, Commercial Manager, Operations Delivery Manager, Head of Business Aviation Delivery, and currently, Head of Aviation Delivery. This role encompasses Gama Aviation Group’s Gama Aviation, myairops, and FlyerTech companies.

In 2023, I was honoured to be invited to serve as the Chair of the Operations Working Group for the British Business & General Aviation Association. This opportunity allows me to contribute to industry initiatives within BBGA’s membership of nearly 200 industry companies, focusing on challenges such as regulatory compliance, Air Services Agreements, technological advancements, workforce development, operational matters, and sustainability.

Marc Bailey

Marc Bailey has spent his entire career in aviation and has worked in most areas of Aviation Services with scheduled airlines, MRO’s, military contract support and latterly with associations, government, and its agencies.

Marc represents your position in Europe (even post Brexit) – as President of ECOGAS (European Council of General Aviation Support) which maintains a voice with EASA. All the major member states are represented on the ECOGAS board. With EASA restructuring its meetings with industry, ECOGAS is now well positioned to represent our position in all areas following industry partnerships with the European Independent Maintenance Group and with ARPAS the new drone and autonomous association.

Marc is chair of the UKASF (United Kingdom Airworthiness Strategic Forum) as part of an initiative to develop Aviation Services across all aviation activities. The UKASF pulls together airlines, MROs, Rotary, Drones, and commercial GA bodies to work with CAA and DfT. The objective is for industry to take the lead to drive strategic issues to benefit all parties. We are well positioned after four years to continue our good work and with the re-established role of Chief Surveyor in the CAA we have a good focal point to do this.

Marc chairs the CAA Finance and Services Forum which allows industry in the UK to discuss in the financial plans for the CAA and the value for money delivered by those funds paid by industry. This is a new and valuable new platform for all parties.

Under recent developments Marc has formed an alliance with, ARPAS, AOPA, BHA and BBGA so that we can strengthen our voice under a joint ‘GA 4 Biz’ banner. This alliance is working to do everything possible to represent the industry’s business interests with UK government and to help realise the Government’s desire to make UK General Aviation a Global Leader in a post Brexit environment. GA4Biz – GA4Biz

The next Generation initiatives with industry and government have continued to develop with the retention platform now evolving into the “Aviation Skills Recruitment Platform”. The platform now not only offers a vehicle for those offering and seeking posts in aviation, it also provides pathways with its TalentView portion seeking to provide pathways for new entrants into our sector. The recruitment platform is being further developed to include training opportunities across a wide range of providers, from government agencies through academic bodies. Getting our next generation activities right in the UK over the next couple of years is our single most important issue which we in aviation must grab with both hands. Marc is playing a central role to help develop many of these channels.
