Recent trends and biases in mesophotic ecosystem research

Area of Science:

• Marine Biology
• Oceanography
• Ecosystem Research

Background:

• Mesophotic ecosystems, spanning 30-150 meters, constitute a substantial part of the world's oceans.
• Historically, these ecosystems have been understudied due to accessibility challenges.
• Recent technological advancements and increased scientific interest have spurred research in both tropical and temperate mesophotic environments.

Purpose of the Study:

• To analyze global research trends in mesophotic ecosystems.
• To identify and characterize biases in current mesophotic research efforts.
• To inform future research directions and stimulate discussion in this emerging field.

Main Methods:

• Utilized the updated 'mesophotic.org' database (www.mesophotic.org).
• Reviewed and cataloged 1500 scientific publications on mesophotic ecosystems.
• Analyzed publication data to identify trends and imbalances in research.

Main Results:

• Identified four major research biases: geographical spread, focal depth range, research fields (organisms and platforms), and lack of temporal studies.
• Documented a significant imbalance in the geographical distribution of mesophotic research efforts.
• Highlighted disparities in the depth ranges and research approaches within the mesophotic zone.

Conclusions:

• Despite identified biases, there is optimism for the future of mesophotic research.
• Awareness of current trends and imbalances can guide future scientific endeavors.
• The study aims to stimulate focused discussion and strategic planning for mesophotic ecosystem research.
