Researchers from Cefas, Marine Scotland Science and the University of Exeter have collaborated to analyse the first UK underwater noise data.

The Centre for Environment, Fisheries and Aquaculture Science (Cefas) has teamed up with Marine Scotland Science and the University of Exeter to analyse underwater noise data from subsea sound recorders located around the UK coast. The results of the Defra-funded study have now been published in an article titled Underwater noise levels in UK waters in the Nature journal Scientific Reports.

Sources of noise in the ocean include shipping, seismic exploration, and construction activity, such as port extensions or offshore wind farms. There is concern that rising levels of underwater noise pollution worldwide may have an impact on marine life by interfering with communication, causing changes in behaviour, and raising stress levels.


For the first time, the team has drawn together measurements from around the UK coast to make an assessment of underwater noise pollution. They found that many sites were exposed to persistent noise from shipping traffic, while other locations were comparatively undisturbed. In addition to shipping noise, the team also identified noise from onshore industrial activities, fishing, and acoustic deterrent devices (ADDs; also known as ‘seal scarers’).

The study will inform UK policy on underwater noise pollution, and forms the basis of the UK assessment of underwater noise under the EU Marine Strategy Framework Directive (MSFD), which assesses the status of European seas.

Cefas Principal Scientist and lead author of the paper, Dr Nathan Merchant said:

“This is the first time we have had an overview of noise levels around the UK, which means we now have a benchmark against which to measure future changes in noise pollution. Ongoing noise monitoring at these sites will allow us to see whether efforts to reduce noise pollution are effective, and if the pressure on marine ecosystems from manmade noise is rising or falling.”


Dr Kate Brookes, Renewable Energy co-group leader, Marine Scotland Science said:

“Understanding current noise levels underwater, and the effect these have on marine wildlife is critical to allowing us to develop plans to manage human activities. Marine Scotland Science have been monitoring ambient noise levels off the Scottish coast for four years as part of the ECOMMAS project (East Coast Marine Mammal Acoustic Studies) and the inclusion of these data alongside others from the rest of the UK present the first opportunity to understand how levels vary around the UK.”

Dr Matthew Witt, Senior Lecturer in Natural Environment, University of Exeter said:

“The opportunity to contribute valuable data to this partnership helps further demonstrate the importance of universities and the cutting-edge research they deliver to society, industry and Government. Of great importance to us is the development of a coherent policy on underwater noise pollution, built upon a robust evidence-base, that helps to limit the insidious effects of human noise on our coastal ecosystems, particularly given the important role these ecosystems play in Earth’s life-support systems.”

Cefas is currently working in partnership with several UK universities to establish a permanent noise monitoring network, which will become operational in 2017.

Want to Connect With Nature? Start by Disconnecting From Busyness

Connect With Nature

Have you ever found yourself staring at one of your (many) devices and feeling slightly disgusted with how much time you waste on technology? If so, you aren’t alone. We all have moments like these and it’s important that we use them as motivation to change – especially if we want to be more connected with nature.

How Busyness Impacts Your Connection With Nature

Whether you realize it or not, you live an ultra connected life. Between smart phones, tablets, computers, and wearable devices, you’re never very far from some sort of technology that can connect you to the internet or put you in touch with other people. That’s just the world we live in.


While it could be argued that this sort of omnipresent connectivity is a positive thing, it’s also pretty clear that being permanently tethered to technology impacts our ability to strip away distractions and connect with nature.

When you’re always within arm’s reach of a device, you feel a sense of busyness.  Whether it’s browsing your social media feed, uploading a picture, reading the news, or responding to an email, there’s always something to do. As someone who wants to spend more time in nature, this is problematic.

4 Practical Ways to Disconnect

If you want to truly connect with nature and live a greener lifestyle, you have to be proactive about finding ways to disconnect. Here are a few practical suggestions:

1. Switch to a New Phone Plan

It’s not always practical to totally unplug from the world. Family and work responsibilities mean you can’t go off the grid and continue to fulfill your responsibilities. Having said that, there are some ways to scale back.


One suggestion is to switch to a prepaid phone plan. When you have a prepaid phone plan, you’re far less likely to spend hours and hours of your time making phone calls, sending texts, and surfing the web. It forces you to be more conscious of what you’re doing.

2. Get Rid of Social Media

Social media is one of the biggest time wasters for most people. Whether you realize it or not, it’s also a huge stressor. You’re constantly being exposed to the best snapshots of everyone else’s lives, which makes you feel like you’re missing out on something (even when you aren’t).

If you want to feel a sense of relief and free yourself up to spend more time in nature, get rid of social media. Don’t just delete the apps off your phone – actually disable your accounts. It’s a bold, yet necessary step.

3. Create Quiet Hours

If you aren’t able to get rid of social media and disable various online accounts, the next best thing you can do is establish quiet hours each day where you totally detach from technology. You should do this for a minimum of three hours per day for best results.

4. Build Community

Do you know why we’re drawn to social media and our devices? Whether consciously or subconsciously, it’s because we all want to be connected to other people. But do you know what’s better than connecting with people online? Connecting with them in person.

As you build real life, person-to-person relationships, you’ll feel less of a need to constantly have your eyes glued to a screen. Connect with other people who have an appreciation for nature and bond over your mutual interests.

Untether Your Life

If you find yourself constantly connected to a device, then this is probably a clear indicator that you aren’t living your best life. You certainly aren’t enjoying any sort of meaningful connection with nature. Now’s as good a time as any to untether your life and explore what a world free from cords, screens, and batteries is really like.

6 Tips for an Eco-Friendly Move

Published

on

Moving can be a stressful and challenging time. No matter how many times you’ve done it in the past, the process of packing up, transporting, and unpacking isn’t very fun. It’s also not very eco-friendly. As you prepare for your next move, there are things you can do to ensure you leave less of a footprint behind.

6 Tips for a Greener Move

Because of the stress and pressure felt when moving, it’s pretty common for people to rush through the process and focus on getting it done. In fact, a lot of people take an “at all costs” approach; they’ll do whatever it takes to make the process as cheap and fast as possible. Don’t be one of those people. It doesn’t take much effort to turn a standard move into an eco-friendly move.


1. Maximize Each Trip

When moving across town, it’s imperative that you make as few trips as possible. Each trip requires more gas, more emissions, and more waste, and more time.

If you’re taking your personal vehicle, consider pulling a trailer behind it. You’d be surprised how much stuff you can fit into a small trailer. Not only will it make your move greener, but it’ll also save you a lot of time.

2. Donate Things You Don’t Want to Keep

The longer you live somewhere, the more junk you accumulate. This isn’t always obvious until you start packing for a big move. Instead of bringing all of these things with you to your next home, get rid of the stuff you don’t need! If the items are useful, donate them. If the items don’t have much value, toss them.

3. Reuse Moving Boxes

Not only are moving boxes expensive, but they’re also wasteful. If you need a bunch of cardboard boxes, consider looking around on Craigslist, asking friends, or checking the dumpsters behind stores. You can usually find a bunch of recycled boxes of all different shapes and sizes. Here are 12 places you can get them for free.


4. Get Creative With Packing

Who says you need moving boxes? You may find that it’s possible to do most of your move without all that cardboard. Things like storage containers, trashcans, filing cabinets, buckets, and dressers can all store items. Blankets and sheets can be used in lieu of bubble wrap to prevent your items from getting damaged.

5. Use Green Cleaning Supplies

Once you arrive at your new place, resist the urge to pull out a bunch of harsh chemicals to clean the place. You can do yourself (and the planet) a favor by using green cleaning supplies instead. Ingredients like vinegar, baking soda, and ammonia are great to start with.

6. Forward Your Mail ASAP

Don’t delay in forwarding your mail from your previous address to your new one. Not only is it wasteful for the Postal Service to route your mail to a place where you don’t live, but the next owner is probably just going to toss your letters in the trash.

Moving Doesn’t Have to be Wasteful

Most people only move once every few years. Some people will go a decade or more without a move. As a result, the process of moving often feels strange and new. The less experience you have with it, the less likely it is that you’ll be as efficient as you should. But instead of just diving into the process blind, take some time to learn about what an eco-friendly move looks like. That way, you can leave behind the smallest footprint possible.
