Some great underwater pictures from Antarctica

You may remember that back in January we told you about Jennifer Loxton's trip to the Antarctic to study environmental conditions beneath the waves using HOBO U24-002 Data Loggers.

Well, she's back (Despite what her blog says!). Be sure to check out some of the fantastic photo's on her blog here.

New HOBO® Event State Data Loggers launched

We're delighted to announce the new HOBO® UX90 Series of data loggers. With the introduction of the UX90 range of HOBO data loggers, Onset can now boast the industry’s lowest-cost, most comprehensive family of “time-of-use” data loggers. The new toolbox suite includes LCD-display data loggers for measuring motor on/off status, electronic pulses, state changes, and occupancy and light use patterns.

• LCD displays On-time or % On, providing instant feedback
• Auto-calibration & signal strength indicator ensure proper deployment
• 84k or 346k measurement capacity enables longer deployments with fewer site visits
• Rare Earth Magnets, 3M Command™ Strips or mounting tabs for reliable mounting
• Flexible logger Start and Stop options
• HOBOware® Pro’s time-saving features allow for easy set-up of hundreds of loggers

HOBO U24-002s off to Antarctica!

Thankfully, we don’t have to brave the extreme conditions that Jennifer Loxton, of Heriot-Watt University, will be facing.

Jennifer has been awarded funding from British Antarctic Survey, NERC and the Heriot Watt Alumni Fund to support a project investigating the effects of climate change in Antarctica. The project is collaboration between scientists from Heriot-Watt University, the Natural History Museum (NHM), and the British Antarctic Survey (BAS).

Jennifer will join scientists from the British Antarctic Survey (BAS) on an expedition to the Antarctic Peninsula, to spend 6 weeks in Jan/Feb 2012 SCUBA diving in one of the most extreme diving locations on the planet. During this time she will be examining and collecting bryozoans, small colony forming marine invertebrates, in order to understand the effects of ocean acidification and climate change on their calcium carbonate skeletons.

 Animals such as bryozoans, with their small size and fragile skeletons, are best retrieved from the seabed by hand. However, diving in the waters of the Southern Sea is not something to be taken lightly. Antarctic diving poses many interesting challenges because the sea surface freezes and the water temperature at Rothera is below -1 °C most of the year and rarely reaches +1 °C. Weather, such as high wind speeds, icebergs scouring the seabed, leopard seals and killer whales also mean much care is required as well as specialised training and kit.

 The marine invertebrates chosen for this study are tiny marine animals called bryozoans; these filter feeders live together in colonies and build intricate and chemically complex calcium carbonate skeletons. Bryozoans are of interest to scientists studying climate change as they are able to vary the composition of the calcium carbonate as a response to changing conditions in the water they live in. Jennifer will be analysing the skeletons of three of the most common Antarctic species in order to understand the patterns of this variation and therefore gauge the actual effects of climate change on Antarctic animals.

We’re always excited to learn where our data loggers end up and, as Jennifer is planning to use HOBO U24-002 Conductivity/salinity Data Loggers supplied by us, we’ll be keeping an eye on Jennifer’s blog and tweets. I suggest you do as well.

Hobo U24 Data Logger in action

A few weeks ago, we told you about the new HOBO U24 data loggers. These data loggers are ideal for tracking and monitoring water temperature changes in both salt and freshwater conditions.

Cape Cod Times/Merrily Cassidy

Just last week, a colleague pointed them out being used in: Sandwich, Massachusetts by Jo Ann Muramoto (Senior scientist from the Association to Preserve Cape Cod) as part of a Statewide Project to gauge the impact of global warming on river herring.

It's always great to see advances in technology leading to practical experiments and analysis that weren't feasible before.

New HOBO Conductivity and Salinity Data Loggers

We've had great feedback about Onset's new HOBO Conductivity and Salinity Data Loggers


There are two models to choose from for fresh and salt water deployments. Both provide easy access to the sensor for cleaning and shedding air bubbles. HOBOware Pro software enables start/end-point calibration to compensate for any fouling and provides easy conversion to specific conductance and salinity.

Fresh Water Option
Hobo Conductivity Data Logger - U24-001

Supported Measurements: Conductivity, Temperature
Ideal for streams, lakes, and other freshwater sources
Non-contact sensor reduces sensor drift
Conductivity range from 0 to 10,000 µS/cm
Easy access to sensor for cleaning

Salt Water Option
HOBO Conductivity Data Logger - U24-002

Supported Measurements: Conductivity, Salinity, Temperature
Ideal for saltwater environments such as bays and estuaries
Conductivity range from 100 to 65,000 µS/cm
Non-contact sensor reduces sensor drift
Easy access to sensor for cleaning

Track Energy Consumption Easily

Onset's new 4-channel energy data logger combines the functionality of four separate data loggers into one compact unit.

Enabling energy management professionals to track energy consumption, equipment runtimes, and water and gas flow rates.

The UX120 Simultaneously measures and records pulse signals, events, state changes, and runtimes
With onboard storage of over 4 million measurements you can now deploy for longer with fewer site visits needed.

The range of start/stop options, logger status LEDs, and high-speed USB 2.0 data offload enable you to deploy the unit much more easily.
