Navigating historical passages of marine invasive species
Invasive species are a persistent threat to marine ecosystems. In this post, authors explore the historical context of marine invasive species and point toward the need for the public to be engaged in preventing the spread of invasive species. Katherine BarrettKate is a 2nd year PhD student in the Biological Sciences Department at the University […]
Microbialites are the unseen power house for marine and inland sea ecosystems
Ever hear someone say, “Just because you can’t see something, doesn’t mean it’s not there?” Well, microscopic bacteria and algae are hard to see, but they play an important role in marine ecosystems, and in some cases, many different types of bacteria and algae grow together and produce large reef-like structures. Read on to find […]
Hope in isolation: four small islands are defying current threats to ocean health
Would you believe me if I told you that the oceans still possessed pristine, unimpacted habitats? In an age where we are learning more and more about how multiple stresses-from climate change to increasing pollution-are hurting our oceans, one recent study has shed light on the remarkable healthy ecosystem of a group of small islands […]
Linking marine and human health in Hispaniola
Biodiversity is often associated with higher standards of human livelihood, but researchers have yet to draw a direct line between healthy marine ecosystems and humans. Read on to learn how national infrastructure can complicate the relationship between biodiversity and human health. Katherine BarrettKate is a 2nd year PhD student in the Biological Sciences Department at […]
Power by the numbers: tiny shrimp generate turbulence in the ocean
Imagine hundreds of thousands of tiny shrimp swimming in the ocean. Believe it or not, the combined swimming action of these ocean dwellers can generate large-scale mixing of the ocean water column. Read on to learn more about these incredible ocean mixers. Katherine BarrettKate is a 2nd year PhD student in the Biological Sciences Department […]
Honey I shrunk the….fish?
What we know about commercial fishing’s repercussions on reef fish is more complicated than just reducing the size of their populations. Commercial fishing exploits are driving some fish species to become smaller. Read on to find out more and how marine protected areas may be critical to the recovery of exploited fish populations. Katherine BarrettKate […]
Tracking predators in seagrass beds
Scientists have long recognized that predators are more abundant at lower compared to higher latitudes. Read more to find out how a group of marine ecologists investigated the importance of predator-prey interactions in seagrass beds. Katherine BarrettKate is a 2nd year PhD student in the Biological Sciences Department at the University of Notre Dame, and […]
Restoring the links between land and sea
On February 2, we celebrated World Wetlands Day. Wetlands, some of the most productive ecosystems on earth, are threatened. Read on to learn how salt marshes, a type of wetland, can be restored after decades of degradation. Katherine BarrettKate is a 2nd year PhD student in the Biological Sciences Department at the University of Notre […]
Marine diatoms eat climate change’s dust
Multiple, interacting factors from climate change make it difficult for scientists to predict how marine life will respond to climate change. Read on to find out how researchers studied the effects of dust deposition, ocean warming, and increased carbon dioxide concentrations on a common marine diatom. Katherine BarrettKate is a 2nd year PhD student in […]
Corals get their auras read
Corals, depending on dominant cover type, can influence the microbial community living in the surrounding water. Read on to find out more about the coral aura-biome. Katherine BarrettKate is a 2nd year PhD student in the Biological Sciences Department at the University of Notre Dame, and holds a Masters in Environmental Science & Biology from […]
Beyond word of mouth: How local knowledge can fill fisheries data gaps
How can we accurately assess the extent of population declines in marine organisms? Read on to find out how local and traditional knowledge can inform future fisheries management by recounting past experiences. Katherine BarrettKate is a 2nd year PhD student in the Biological Sciences Department at the University of Notre Dame, and holds a Masters […]
How to model climate change in an Arctic food web
The climate is changing, and so are Arctic food webs. But our knowledge of how food webs respond to warmer Arctic water temperatures is incomplete, so scientists use models to help further understanding of future food web scenarios. Katherine BarrettKate is a 2nd year PhD student in the Biological Sciences Department at the University of […]
How to clean a sea turtle
Could you imagine if you had to actively seek out showering stations to stay clean? For sea turtles, they must search for cleaning stations. Katherine BarrettKate is a 2nd year PhD student in the Biological Sciences Department at the University of Notre Dame, and holds a Masters in Environmental Science & Biology from SUNY Brockport. […]
Wandering copepods can’t find their way home in acidic oceans
Journal source: Smith, J. N., C. Richter, K. Fabricius, and A. Cornils. 2017. Pontellid copepods affected by ocean acidification: A field study at natural CO2 seeps. PLoS ONE 12 doi: https://doi.org/10.1371/journal.pone.0175663. Introduction Ocean acidification (OA for short) is a topic that seems to be receiving increased attention, and if you’ve scrolled through some recent Oceanbites posts, […]
Wake up and smell the marine awareness…on social media?!
Close your eyes and imagine your favorite beach, or a memorable coast you have visited, completely free of litter-that’s right, no plastic bottles, no garbage, no microplastics, no wandering potato chip bags. Is this vision possible? Take a moment, or 3, and see what you can do to reduce marine pollution! Katherine BarrettKate is a […]
Paleoshorelines: Time capsules of the ocean’s ancient shorelines
In celebration of World Ocean’s Week, let’s take a moment to think about how far we have come in discovering the history of the oceans. Katherine BarrettKate is a 2nd year PhD student in the Biological Sciences Department at the University of Notre Dame, and holds a Masters in Environmental Science & Biology from SUNY […]
Tarballs invading our coastlines: Ghosts of oil spills past
We live in a world that is torn between reliance on fossil fuels and renewable energy. Although we have made great strides towards increasing wind and solar energy, the ghosts of oil spills past are washing up on our shorelines. Katherine BarrettKate is a 2nd year PhD student in the Biological Sciences Department at the […]
Best of both worlds: stromatolites of the intertidal zone
Did you know that the earliest form of life on Earth can still be found today? Read more to find out how researchers studied ancient formations called stromatolites growing within the intertidal zone of Cape Elizabeth, South Africa, and how salinity and nutrients influence these rare structures. Katherine BarrettKate is a 2nd year PhD student […]
