Humpback whales have arrived in Monterey Bay–and we have the best seats in the house. These graceful giants have been breaching, spouting and feeding just off our decks!  These massive mammals use air bubbles to herd and corral schools...Show More Summary

Ten Simple Rules for Effective Online Outreach

Exciting news for the DSN team! What we do here on this site — our mission and core values — have now been immortalized in the peer-reviewed scientific literature. Yeah, baby! It’s been a long time in the making, but we’re so happy to announce the publication of “Ten Simple Rules for Effective Online Outreach”, a new […]

Which way does an octopus crawl? Anyway it wants.

Let’s face it, octopuses are just going to be our cephalopod overlords. They have 8 arms, 3 hearts, Moms eat their own babies so the others can survive and they put Houdini to shame with their escape artistry. And now let’s just add to the list that they are way better at crawling than we will ever […]

The perennially popular penguin There are few things in life cuter than a penguin. OK, maybe when a penguin waddles, especially if there are more than one and it’s actually a parade! The colony of African blackfooted penguins (Spheniscus demersus) in our Splash Zone family gallery is a must-see on any visit. Show More Summary

The Southern Ocean ecosystem under multiple climate change stresses – an integrated circumpolar assessment

A quantitative assessment of observed and projected environmental changes in the Southern Ocean (SO) with a potential impact on the marine ecosystem shows: (i) large proportions of the SO are and will be affected by one or more climate change processes; areas projected to be affected in the future are larger than areas that are […]

Effect of climate change on crustose coralline algae at a temperate vent site, White Island, New Zealand

Natural CO2 vents allow study of the effects of climate change on marine organisms on a different scale from laboratory-based studies. This study outlines a preliminary investigation into the suitability of natural CO2 vents near White Island, Bay of Plenty, New Zealand (37°31.19?S, 117°10.85?E) for climate change research by characterising water chemistry from two vent […]

Subaqueous soils and coastal acidification: a hydropedology perspective with implications for calcifying organisms

In the coastal zone, biological and biogeochemical processes, influenced by anthropogenic inputs, drive pH variability and contribute to coastal acidification. Spatial patterns of these processes across coastal estuaries are unknown....Show More Summary

Environmental physiology of the jumbo squid, Dosidicus gigas (d’Orbigny, 1835) (Cephalopoda: Ommastrephidae): implications for changing climate

Dosidicus gigas (d’Orbigny, 1835) is a large, active squid that undergoes a diel vertical migration in the Eastern Tropical and Temperate Pacific. It is a voracious predator on zooplankton and micronekton and supports a large fishery. It is further preyed upon by large vertebrate predators, including whales. Its horizontal distribution is closely tied to productive […]

Changes in pteropod distributions and shell dissolution across a frontal system in the California Current System

We tested the sensitivity of the vertical distributions and shell dissolution patterns of thecosome pteropods to spatial gradients associated with an eddy-associated front in the southern California Current System. The aragonite saturation horizon (?arag = 1.0) shoaled from >200 to <75 m depth across the front. Show More Summary

Morphology and classification of hemocytes in Pinctada fucata and their responses to ocean acidification and warming

Hemocytes play important roles in the innate immune response and biomineralization of bivalve mollusks. However, the hemocytes in pearl oysters are poorly understood. In the present study, we investigated the morphology and classification of hemocytes in the pearl oyster, P. Show More Summary

Captivated yet? This small but feisty flamboyant cuttlefish is unlike the rest, walking along the seafloor on arms and fins–and flashing its hypnotic color scheme to scare off predators. Learn more about this impossibly colorful cephalopod

Climate driven variability in the Southern Ocean carbonate system

We investigate seasonal and interannual variability in the Southern Ocean carbonate system using output from a historically forced (1948-2007) ocean general circulation model with embedded biogeochemistry. Atmospheric CO2 is fixed at pre-industrial levels to investigate carbonate system variability in the absence of an anthropogenic CO2 perturbation. Show More Summary

Effects of elevated CO2 levels on eggs and larvae of a North Pacific flatfish

The Bering Sea and Gulf of Alaska support a number of commercially important flatfish fisheries. These high latitude ecosystems are predicted to be most immediately impacted by ongoing ocean acidification, but the range of responses by commercial fishery species has yet to be fully explored. In this study, we examined the growth responses of northern […]

Effects of CO2 and iron availability on rbcL gene expression in Bering Sea diatoms (update)

Iron (Fe) can limit phytoplankton productivity in approximately 40% of the global ocean, including in high-nutrient, low-chlorophyll (HNLC) waters. However, there is little information available on the impact of CO2-induced seawater acidification on natural phytoplankton assemblages in HNLC regions. Show More Summary

Jump for joy! We’ve been seeing humpback whales off our ocean-view decks this week. These mega-mammals are on the hunt for schools of fish and krill, which they round up by blowing bubbles! Learn more (Photo: Giancarlo Thomae/kayakwhalewatching.com)

Biologist studies how the increasing acidity that has come with climate change is affecting ocean life

The increasing acidity of the world’s oceans is having some pretty dire effects, including damaging coral reefs and weakening the shells of clams, oysters and mussels. Acidification is also harming sea creatures at the bottom of the oceanic food chain, such as plankton and fish larvae, posing a threat to many species of marine life. […]

??New carbonate system proxies: foram culturing and pteropod potentials

Global climate change is one of the most pressing challenges our society is facing currently. Climate sensitivity due to atmospheric CO2 doubling will most likely increase global temperatures by 2.0 – 4.5 °C (IPCC 2007). While some direct effects of increasing CO2 are straightforward (e.g. ocean acidification, atmospheric temperature rise), the mid- and long-term impacts […]
