The #regionalcabledarray is immensely important in terms of the science that it addresses through the myriad of high quality datasets streamed to shore in real time. But it also offers a unique opportunity for everyone to view a variety of rarely seen seascapes. We have a vast repository of high quality photos, videos, and data from all of the RCA research sites. In concert, this archive allows anyone interested in the oceans to explore the amazing environments that the array is monitoring “hidden” beneath the waves. Here is a highlight video from a 2019 survey of Southern Hydrate Ridge (offshore of Oregon) sped up to 4x normal speed so you can get a sense for the intense and unusual biogeochemical activity at the site! .

Welcome to Hell! Well, the hydrothermal vent nicknamed ‘Hell' (for the scorching geothermal fluids that seep out). In this instance, Hell is inhabited by tubeworms, bacteria, sea spiders, and scale worms that thrive in the boiling hot seawater (and create energy using the dissolved minerals that come with it). Many individual photos were stitched together to create this intricate, ‘hellish’ photomosaic. PC: M.

Creature Feature Friday! Today the turn belongs to the Giant clam! Called giant for a reason, these molluscs can reach over 1m in length and can weigh over 225kg! The largest sessile mollusc, once it fastens itself to a rock it cannot move. They have a symbiotic relationship with an algae which lives in their tissues - it produces sugars and protein for the clam whilst the clam provides protection and access to sunlight. The colouration on the mantle is unique to each clam. Giant clams have been growing on coral reefs for over 38,000,000 years and are very important to the health of the reefs as they undertake numerous roles in the ecosystem. For example, they can help build and shape reefs, they provide food and shelter for other creatures and act as reservoirs for algae. Unfortunately, populations are in decline as the muscle is considered a delicacy in some countries. The aquarium trade is another contributing factor #onlywithwiseoceans #creaturefeature #creature #friday #giantclam #clam #uwoceanography #mauritius #oceans #marineeducators #marineducation #marineconservation #marinewildlife #marinescience #marinelife #marinebiology #sea #educate #inspire #empower #togetherwecan #protecttheocean #savethesea #getwoketotheplanet #oceanphotography #oceanlife #sea #reef

Here we have no ordinary pig here: The TRHPH also known as a “Pig” (because of its looks) or “Res Probe” (short for resistivity probe)is a novel seafloor instrument designed to go inside the “throats” of high-temperature (>400°C) black smoker chimneys to measure the resistivity and temperature of the hydrothermal vent fluids. Resistivity is an analogue for chlorinity, measuring the “saltiness” of the vent fluids. Some structures at Axial Seamount emit boiling fluids, as reflected by their high temperature and low chlorinity. These hydrothermal vents also have very low pH (~1.0, lower than battery acid), which makes long-term measurements very challenging, but with the help of our “pigs” it is easier. .

Eyes in the ocean! Collecting continuous underwater images is challenging; one way this is made easier is through the use of sub-sea cameras. We have underwater cameras across the array from shallow to deep water environments, regularly documenting how these environments change. . Imagery for OOI is collected to support a wide range of science questions, from geology to biology. Subjects of interest include changes in animal population density and activity, details of microbial mat development, vent and seep flow rates and morphologic changes over time, and sedimentation processes. The cameras need the ability to image sediment and rock surfaces in sufficient detail to identify organisms (e.g., sea pens, fish, crustaceans, etc.), examine changes in the seafloor like ripples in the sediment, and identify features such as tracks and trails made by mobile fauna. Color images are required to assist with organism identification and to image marine snow falling to the seafloor. .

Pies in the ocean? HPIES of course, These instruments, also known as Horizontal Electric Field, Pressure and Inverted Echo Sounder, measure water column properties throughout the entire water column in combination with other instruments (more below). . HPIES utilizes a bottom pressure sensor, a 12-kHz inverted echosounder, and a horizontal electrometer to measure the horizontal electrical field, the bottom pressure, and the vertical acoustic travel time from the sea-floor to the sea-surface. These properties provide insights into the vertical structure of current fields and water properties including temperature, salinity, and specific volume anomaly, separation of sea surface height variation and temperature, and near-bottom water currents from ocean depths as great as 2900 m. .

Deep Profiler Day!! The #regionalcabledarray includes three mooring sites that each host a cabled Deep Profiler: one at the base of the subduction zone (Slope Base – 2900 m), one on the Oregon Margin (OR Endurance Offshore – 600 m) and one at the base of Axial Seamount (Axial Base – 2700 m). The Deep Profiler mooring is a single cabled, vertical mooring that hosts a modified @mclane_research_labs wire-following vehicle carrying instruments that measure ocean properties from ~2900 m to ~ 150 m water depth. Live command and control capabilities occur at the UW Operations Center and real-time data are streamed to the UW RCA Operations Center and into the @oceanobservatories_initiative Data Portal. The moorings are designed to measure global and local currents, megaplumes, ocean chemistry (e.g. pH, CO2, nutrients), heat flux, thin layers, and biological parameters (e.g. zooplankton time series distribution and chlorophyll). Included are images and a gif of the Deep Profiler at work, and a plot of temperature over 3 months from the Axial Base Deep Profiler. .

When measuring the ocean, it is always smart to start with the basics: taking its temperature! Making regular thermal, salinity, and pressure measurements of the ocean is a standard marine science practice. These three parameters are considered “key variables” in the ocean as they influence nearly all other ocean parameters such as seawater density, circulation, and chemistry, as well as the organisms that live there. A CTD is an instrument used to determine how conductivity (C) and temperature (T) measurements in the ocean vary relative to depth (D) and is our primary tool for measuring physical properties of the ocean. Salinity is calculated from electrical conductivity and is a measurement of the concentration of salt and other inorganic compounds in seawater. The #regionalcabledarray has CTDs spanning near shore to deep water environments that are sending back data 24/7 via high power and bandwidth submarine electrical and fiber-optic cables, enabling two-way communication at the speed of light. .

How does one measure flow rates at the ocean-seafloor interface? With Benthic Fluid Flow samplers of course! Our Benthic Fluid Flow samplers measure the speed of seawater flowing in and out of the sediment on the seafloor by monitoring the dilution of a chemical tracer injected into fluids at the seabed. There are two types of flow meters installed on or near methane seeps at Southern Hydrate Ridge that are designed to measure fluids flowing at different speeds: The “C” series of this instrument is a Chemical and Aqueous Transport (CAT) meter. The “M” series of this instrument is a Multiple Orifice Sampler and Quantitative Injection Tracer Observer (MOSQUITO), a fitting acronym since it uses long needles to inject the tracer and “suck” the water out of the seafloor. Both instrument series are recovered annually, the fluids are analyzed for chemical tracer and major ion concentrations, and flow rates are calculated. These instruments are critical to determining the flux of greenhouse gases like methane, bacterial nutrients like hydrogen sulfide, and other naturally-occurring chemicals that are emitted into the overlying ocean. .

Repost from @regionalcabledarray • The ‘Bug Battery’, scientifically known as ‘CH4-BMFC’ or CH4-Benthic Observer Platform, is an instrument and collaborative project between Oregon State University and Harvard University, funded by the Office of Naval Research. The meaning behind the acronym CH4-BMFC is the chemical formula for methane, which bubbles out of the seafloor at Hydrate Ridge in patches that are constantly moving and often hard to find. Along with some other energy-rich compounds, methane serves as a “fuel” to support a large biological community that relies on the ability of microbes to use this compound for energy. The “BMFC” part of our acronym stands for “benthic microbial fuel cell,” which essentially operates like a battery—only this battery is powered by microbes that obtain energy from compounds emitted from the seafloor. This instrument was deployed on VISIONS’19 and recovered this past summer on VISIONS’20. Images above of the CH4-BMFC pre-deployment, during deployment, and once recovered. .

Repost from @regionalcabledarray • Instruments and animals are fun to look at, but so is the substrate they exist on, like these deep-sea lava flows, that extend as far as the eye can see. These flows are the remnants of past eruptions at Axial Seamount, the most recent occurring in 2014. We are ready, waiting, and monitoring for the precursors and signs of an upcoming eruption (like increased seismic activity and inflation of the seafloor from lava chambers below). The last few photos include a spider crab for scale (3 feet across from leg to leg). .

Instruments and animals are fun to look at, but so is the substrate they exist on, like these deep-sea lava flows, that extend as far as the eye can see. These flows are the remnants of past eruptions at Axial Seamount, the most recent occurring in 2014. We are ready, waiting, and monitoring for the precursors and signs of an upcoming eruption (like increased seismic activity and inflation of the seafloor from lava chambers below). The last few photos include a spider crab for scale (3 feet across from leg to leg). .

Snow underwater? While this may look like a snowy landscape, these white covered hills are actually microbial mats! It may be hard to think of microbes as being ‘alive’ but they very much are. Here are some microbial mats near Einstein’s Grotto on Hydrate Ridge, seen during VISIONS’20 at a depth of ~770m below the sea surface. These bacterial mats feed on sulfate, nitrate, and methane bubbling up from beneath the seafloor, and in turn support a wide array of life from other microbes to snails to large rockfish. .

The work the RCA does is often interesting and exhilarating - sometimes though, it is sobering. On one of the dives during VISIONS’20 for the NSF-funded Regional Cabled Array expedition an ‘Orange Crush’ soda can was seen on the seafloor at ~1240m below the sea surface and ~100km offshore. In the remote locations we visit we don’t always know what we are going to see, but trash is never on the list. Please remember to care for the seas; it is where life began and why life continues to exist on this planet. .
