noaasanctuaries: The nutrient-rich waters of Greater Farallones National Marine Sanctuary provide sustenance for major populations of top ocean predators – including white sharks like this one. Each fall, adult and sub-adult white sharks visit the sanctuary in areas where elephant seals and sea lions are abundant. Show More Summary
oceanportal: The basking shark is the second largest living fish, coming in behind the whale shark at a maximum length of about 30 feet (9 meters). Swimming along with its dorsal fin sticking up above the surface of the water, it can easily spook humans. Show More Summary
noaasanctuaries: The NOAA comment period on the review of national marine sanctuaries and marine national monuments has been extended to Monday, August 14! Get the details here. The comment period regards a Department of Commerce review of 11 designations and expansions of sanctuaries and monuments under Executive Order 13795, Section 4(b). Show More Summary
noaasanctuaries: Just a wee little shark! This filetail catshark was spotted at a depth of 470 meters in Sur Canyon in Monterey Bay National Marine Sanctuary. Like cats, filetail catsharks have light-sensitive eyes. This helps them hunt for fish and squid in the dark waters of the deep sea. (Photo: Kevin L. Stierhoff/NOAA)
Take an elasmo-break with our Shark Cam! Watch for sevengill sharks, leopard sharks, spiny dogfish and more as they cruise through the rocky reef in our Monterey Bay Habitats exhibit. ????????????
For a post later, I’ve been watching some old British films involving diving, that this one was just so… I could not resist sharing.
Although the effect of ocean acidification on fertilization success of marine organisms is increasingly well documented, the underlying mechanisms are not completely understood. The fertilization success of broadcast spawning invertebrates depends on successful sperm-egg collisions, gamete fusion, and standard generation of Ca2+oscillations. Show More Summary
The effects of global change on biological systems and functioning are already measureable, but how ecological interactions are being altered is poorly understood. Ecosystem resilience is strengthened by ecological functionality, which depends on trophic interactions between key species and resilience generated through biogenic buffering. Show More Summary
????The public comment period on the review of national marine sanctuaries ends today! Thank you for letting the administration know that the ocean needs more protection, not less.

Welcome home, shark fam! Our tagging research shows that California’s white sharks are landlords with long-term leases, cruising back and forth to their home waters for decades. Check out what we’ve discovered in our Project White Shark update: Episode 2/2 — Shark Fin-gerprints
Presentation on climate change and how it relates to ocean acidification given by Dr Lydia Kapsenberg, post-doctoral researcher, National Science Foundation (USA) & Centre National de la Recherche Scientifique (France), in the framework...Show More Summary
Rising atmospheric CO2 causes ocean acidification that represents one of the major ecological threats for marine biota. We tested the hypothesis that long-term exposure to increased CO2 level and acidification in a natural CO2 vent system alters carbon (C) and nitrogen (N) metabolism in Posidonia oceanica L. Show More Summary
In this study, shell growth, shell microstructure, and expression levels of shell matrix protein genes (aspein, n16, and nacrein) that play a key role in the CaCO3 crystal polymorphism (calcite and aragonite) of the shell were investigated in the pearl oyster Pinctada fucata at pH 8.10, 7.70, and 7.40. We found that the shell length and total weight index did […]
The rise in anthropogenic CO2 and the associated ocean acidification (OA) will change trace metal solubility and speciation, potentially altering Southern Ocean (SO) phytoplankton productivity and species composition. As iron (Fe) sources...Show More Summary
Coastal and estuarine environments are characterised by acute changes in temperature and salinity. Organisms living within these environments are adapted to withstand such changes, yet near-future ocean acidification (OA) may challenge their physiological capacity to respond. Show More Summary
Tuesday, July 25th Grab your binoculars and go to the shore line and see......those images taken from 'the wall' at Lime Kiln Pt. State Park this morning...people were coming down and looking...looking out...looking for the 'big things'...but...Show More Summary
oceanportal: Sharks come in all sizes. The largest is the whale shark, which has been known to get as large as 18 meters (60 feet). The smallest fits in your hand. And the great white shark is somewhere in the middle. See photos and learn more about the wide diversity of sharks, read 5 reasons to revere sharks, and see even more articles about sharks.
