A new species of coral, Christmas Tree Coral (Antipathes dendrochristos), has been discovered in deep waters off southern California. The coral grows up to two meters tall and was first noticed during dives for rockfish surveys.
A team of scuba diving scientists discovered a new type of marine habitat in Alaska's Prince William Sound, specifically rhodolith beds. These colorful algae structures have been found worldwide but never in Alaskan waters, sparking debate over their protection and potential impact on the ecosystem.
A giant fossil coral found in Vanuatu provides evidence of the Younger Dryas period's significant cooling event, which affected the tropics. The coral's growth rate and chemical composition reveal that sea surface temperatures were on average 4.5°C lower than present during this time.
A recent USGS review of scientific literature reveals increased reports of disease outbreaks in turtles, corals, mollusks, mammals, and urchins since 1970. However, no significant trends were detected for seagrasses, decapods, or sharks/rays, with even a decrease in disease reports among fish.
The aquarium trade poses a significant threat to marine and freshwater ecosystems due to the introduction of invasive species. Experts recommend regulating the industry by listing safer alternatives and using bonds to cover potential damage costs.
Researchers have discovered a new family of Atlantic corals using DNA analysis, revealing that about one-third of Atlantic corals are closely related but distinct from Pacific corals. This finding requires reevaluation of conservation priorities for threatened coral species in the Atlantic Ocean.
A groundbreaking study reveals a previously undetected divergence between Pacific and Atlantic corals, finding that about one-third of Atlantic corals constitute their own unique family. This discovery highlights the need to reconsider current conservation efforts due to the severe threats faced by this distinct group.
Deep-sea coral and sponge ecosystems are being destroyed by commercial fishing, especially bottom trawling. Scientists call for governments to protect these newly discovered ecosystems, which provide habitat for marine wildlife and contain chemicals that could become medicines.
Marine biologist Sara Lourie identifies a new species of pygmy seahorse, Hippocampus denise, found in tropical waters of the western Pacific Ocean. The diminutive fish, averaging 16mm in length, may be safe from over-exploitation due to its camouflage abilities.
Researchers have discovered that coral layers in the Atlantic Ocean hold a key to understanding the region's climate dynamics. By analyzing calcium carbonate skeletons, Dr. Lisa Greer and her team found a periodic pattern of oxygen isotope composition with peaks every 12-15 years, mirroring sea surface temperature data.
A study of coral records from the South-West Pacific reveals that El Niño's behavior remained consistent during the Little Ice Age, with no impact on its strength or frequency. The research suggests that massive corals can provide valuable insights into past climatic phenomena.
Scientists have tracked sea level changes and volumes of glacial ice using fossil corals. The study found that sea levels rose too early to be consistent with Milankovitch's orbital forcing, implying other factors can override glacial cycles.
