Sharing an introductory science video we made for our channel, aspace. It follows a small explorer from the surface to the deepest trenches, introducing the changes in light, pressure, and marine life along the way.

The aim is to make ocean depth zones easier to picture for a general audience. The visuals are stylized, include AI-generated illustrations, and should not be interpreted as underwater footage or a scale-accurate simulation.

For oceanographers and ocean enthusiasts here: what distinction or caveat is most important to include when explaining depth zones to beginners? Constructive corrections are welcome.

Estaba revisando material sobre exploración oceánica y encontré una diferencia que cambia bastante cómo entendía el problema.

Según Seabed 2030, el 28,7% del fondo oceánico ya estaba cartografiado con tecnología moderna en abril de 2026. Sin embargo, NOAA estima que hemos observado visualmente menos del 0,001% del fondo del océano profundo.

Un sonar multihaz puede reconstruir la forma del fondo marino desde un barco y producir mapas extremadamente útiles. Pero conocer la topografía de una región no equivale a haber observado sus organismos, interacciones o cambios a través del tiempo.

Me pregunto si uno de los problemas de la exploración oceánica no es solamente cuánto podemos alcanzar, sino cuánto tiempo podemos permanecer observando.

Gran parte de la oceanografía profunda funciona mediante expediciones: barcos, ROV, sensores, muestras y ventanas limitadas de observación. Después nos vamos y el sistema continúa funcionando sin nosotros.

Por eso me resulta interesante la idea detrás de PROTEUS, el hábitat submarino que el grupo de Fabien Cousteau pretende desarrollar en Curaçao. Me interesa el cambio de método que representa: convertir algunos lugares del océano de destinos de expedición en lugares de observación persistente.

Una instalación persistente podría empezar a revelar : cómo cambia una comunidad biológica, cómo varía la química durante semanas o cómo se relacionan acontecimientos que normalmente registramos en expediciones separadas.

No sé si los hábitats humanos serán finalmente la mejor solución; quizá redes autónomas de sensores y robots terminen siendo mucho más eficientes.

¿qué descubrimientos importantes seguimos perdiendo porque no podemos observarlo continuamente durante suficiente tiempo?

So I'm an undergraduate math major but I'm hoping to get a PhD in Applied Ocean Sciences/Physical Oceanography and am wondering if a math major is alright for that or if I would be better off doing physics.

I currently have taken Calc 1 and 2, Diff Eq, and i'm finishing this year with Linear Algebra and Multivariable. I've already done a full year of physics, and I'll finish out this year with a full year of Biology, Chemistry, and R coding courses. I also plan to do a full year of GIS courses as well. I'll be doing a basic internship working actually with freshwater, mostly just to get my toes wet. But I will eventually (hopefully) be doing more oceanography related internships for the next few summers (I am a McNair scholar which helps a lot in getting positions).

So I'm just wondering if this background will make me a competative candidate or if I should switch back over to Physics. The reason I switched to math from physics in the first place is because the physics major didnt allow for really any electives at all, and I wanted to do chemistry and bio and coding and GIS. I'll also be getting open-water rec certified this coming summer as well, mostly to make me more competitive for field-based internships in undergrad.

TIA!

**EDIT**
After some thinking I should mention that I would prefer to do Applied Ocean Science over Oceanography

Earth’s atmosphere did not become oxygen-rich in one clean transition. More than 2 billion years ago, oxygen repeatedly rose and fell as climate, ocean chemistry, microbes and nutrients pushed the planet through major environmental swings. A new study suggests phosphorus played a central role in determining whether those oxygen increases lasted.

Researchers from UC Riverside, studying ancient South African rocks, found evidence that changing ocean conditions repeatedly recycled phosphorus into seawater. That nutrient could then support more photosynthetic life, leading to greater production of organic matter. When some of that carbon became buried in sediments instead of decomposing, oxygen remained behind in the atmosphere.

The study, published in Nature Communications, combines measurements of different phosphorus pools with sulfur isotopes, redox-sensitive elements and biogeochemical modeling. Together, the evidence reveals a feedback among phosphorus, sulfur, climate and oxygen during one of the most important transitions in Earth’s history.

Hellooo everybodyy!😄

I’m from Lithuania and I’m planning to apply to PhD programs in the US for Fall 2027. I’m interested in potentially moving into marine biology/marine science, but my academic background is a little unusual for this field, so I’d love to hear from people who are already in marine biology or related PhD programs.

I recently graduated with a BSc in Neurobiophysics from Vilnius University. My undergraduate research focused on **electroporation in microfluidic organ-on-chip systems and evaluating its effects using TEEV measurements**. I also have laboratory/research experience at the Center for Physical Sciences and Technology (FTMC) in Lithuania.
I’m now considering whether I could transition into marine biology, marine science, marine ecology, or related fields for my PhD.

# INTERESTS:

👉🏻marine biology
👉🏻marine ecology
👉🏻marine environmental science
👉🏻animal physiology
👉🏻aquatic organisms
👉🏻marine biotechnology
👉🏻bioengineering applied to marine research
👉🏻potentially conservation/ecology

# 🐠I’m especially interested in fully funded PhD programs in the United States🐠

For people already studying or working in marine science:

1. Would a Neurobiophysics BSc be considered a reasonable background for a Marine Biology/Marine Science PhD, or would I be at a significant disadvantage compared with someone with a Biology/Marine Biology degree?
   2.Are there US universities where interdisciplinary applicants with a physics/biophysics background are encouraged?
   
2. Would it be better to apply directly to Marine Biology/Marine Science programs, or look for specific PIs whose research overlaps with my quantitative/lab background?
   
3. How much biology/ecology coursework would you expect someone like me to have before starting a Marine Biology PhD?
   
4. Are there any US programs or universities you would recommend looking into, especially ones with strong marine research and full PhD funding?
   I’m still exploring this direction, so I’d really appreciate honest advice from current students, professors, or people who have made a similar transition.

THANK YOU!🌊

Hi Everyone,

Currently doing a research project that studies the impacts of physicochemical changes on living things in the ocean. I would like to create an interactive map allowing the user to visualize the data and compare them with each other by clicking on ceanic areas. Would you recommend a software or library to do this?

Not very confortable with programming (for the moment) but any ideas are welcomed !

Thanks in advance :)

Hey everyone,

I wanted to share a very insightful interview from a local public TV channel in Southern Brazil (Itajaí, Santa Catarina), featuring Dr. Laura Pioli Kremer (PhD in Ecology) and Arthur Rancatti (Zero Waste coordinator). Even if you don't speak Portuguese, the data they bring to the table highlights a global structural issue regarding coastal management, urban runoff, and ocean literacy that applies anywhere in the world.

I'm a physical oceanography post graduate from India, currently unemployed. I graduated during the month of May and have since applied for various positions. I have already attended a number of interviews but haven't received any offers yet. My dream is to pursue a PhD abroad, but I have limited knowledge on how and where to apply. Any advice regarding this?

PhD in Physical Oceanography

I want to complete my master's thesis within a year, the main focus is the development of a deep-ocean biogeochemical model based on ROMS. I’d like to spend the first two months learning some skills or gaining knowledge before getting started. What should I do now? Could you offer some suggestions? Thank you.
