Are you in a healthy relationship with the ocean?

You love the ocean. We love the ocean. Let’s work together to protect it. (PC GGraphics)

Valentine’s Day is all about making sure we don’t take the people we love for granted. Sometimes it feels as though we’re taking the ocean for granted, even though it’s the 71% of the planet that gives us the air we breathe, much of the food we eat, the way we transport goods around the globe, and supports the miraculous wildlife that sparks so much joy. How can we show our love for the ocean?

Right now, people are pulling together to show their love for our endangered orcas any way they can. We use science to find solutions that help us protect endangered species while supporting the people who earn a living from the sea. We are working to reduce bycatch of dolphins, whales, and other ocean creatures by making fisheries more sustainable. Our ongoing efforts to measure and reduce ocean noise can make it easier for whales and dolphins to find food, mates, and navigate an increasingly noisy ocean. Our work on dolphin health provides a glimpse into which pathogens may affect whales, dolphins, and other marine mammals in the Pacific Northwest, and aims to draw a direct link between what we dump into the sea and how the ocean ecosystem is affected.

You don’t have to be a marine biologist to have a positive impact on ocean conservation. The choices we make as consumers can have a ripple effect that encourages industry and policy-makers to embrace ocean-friendlier practices.

Here are five ways to show your love for the ocean. What did we miss? Please share your ideas in the comments!

  1. Reduce your plastic use. Pass on the plastic straw and use re-usable cups. Some of our favorite go-to thank-you gifts are these custom Oceans Initiative pint cups and coffee mugs from our friends at MiiR.
  2. Buy locally and support local artists: 90% of everything comes to us from ships, which are important sources of carbon emissions and underwater noise. Buying locally reduces our shipping footprint. This year, a lot of our gifts include sweets from Seattle-based Joe Chocolates and custom orca stickers from the talented artist, Sophia Trinh. Sophia even offers painting classes, so you can give the gift of experiences, not things.
  3. Choose and support sustainable seafood: Ask your local grocer, farmer’s market, and restaurant about the source of their seafood. It makes a difference. Aim for wild, locally caught seafood that has MSC certification. If you already do this, you can go further to help southern resident killer whales. In the wake of the tragic story of Talequah and the ongoing struggle of the orcas, Chef Renee Erickson made a bold decision last summer to pause serving Chinook salmon in her restaurants. We love giving Renee’s excellent cookbook to our friends and family. Feeling bold? Eat invasive species! Totally guilt-free eating. You’re doing the ocean a favor.
  4. Get out and enjoy the ocean! Go for a walk on the beach, organize a local beach clean-up, surf, paddle, sail, learn about a new whale, fish, or other sea creature, paint or create your favorite ocean art. Have a nap on the beach.
  5. Find a marine conservation nonprofit whose work you like, and support it. Spread the word about their work. Convince a friend to support it. Make a charitable donation in the name of someone you love. It doesn’t have to be us (but we’d be thrilled if you did support our work, of course). Honest. Find the group whose mission sings to you, and get involved.
Pacific Northwest classic gifts (clockwise from top left): Chef Renee Erickson’s cookbook is a love song to the Pacific Northwest; Sophie Trinh’s whale stickers and paintings are magical (& she even offers painting lessons); Joe Chocolate is a sweet, local company; and MiiR’s reusable cups and mugs are lovely and handy in a town that runs on coffee. What are your go-to gifts?

How do you show your love for the ocean?

Southern Resident killer whale monitoring on San Juan Island

by oceansadminConservation, Human Impacts, Killer Whale Conservation, Ocean Noise, Protecting Species, Whales, Women in SciencePosted on No Comments

This summer, from mid-July to the end of September, we studied southern resident killer whale behavior under varying levels of boat and ship traffic. (This is an extension of our 2017 field season with OrcaSound). The Port of Vancouver has asked ships to slow down to less than 11 knots as they transit Haro Strait. Reducing ship speed can reduce shipping noise underwater, but slower speeds mean those ships take longer to transit the area. Working with Port of Vancouver and SMRU Consulting, we are exploring how whales navigate that trade-off between noise level and duration of exposure.

Do the whales find more salmon if they are exposed to a little bit of noise for long periods of time? Or is it better to get the noise over with quickly? 

Reducing noise is especially important because endangered southern resident killer whales (SRKW) feed in Haro Strait in the summer, and our work has shown that vessel noise disrupts killer whale foraging. While missing one meal might not seem like it would have long-lasting or population-level effects, Haro Strait is a noisy place, which may result cumulatively in many lost meals for the killer whales. We had our team on the western hillsides of San Juan Island all summer to track killer whales in an effort to find out if and how their behavior changes with the slower, quieter ships.

To track these whales, we used an instrument called a theodolite. You may have seen them on construction sites or traffic surveys. A theodolite has a telescopic lens that we use to track killer whale movement. After setting a constant reference point, the theodolite can determine the angle between the reference point and the whale we’re looking at. It gets the vertical angle from a gravity-referenced level vector. A computer connected to the theodolite can use those two angles (along with the precise location and elevation of the theodolite) to estimate distances and fixed positions of objects on the ocean’s surface (whales, ships, etc). Your geometry teacher was right—this math does have real-world applications. And we can get all of this fine-scale information noninvasively, without another research boat confounding the effect we are trying to measure. This year, the developer of Pythagoras software generously shared code to let us integrate extremely high-resolution AIS data on the movement of ships, so we could automagically collect precise and accurate data on the ships, while having our expert observers concentrate on measuring the whales’ behavior.

In 2017, the killer whales were worryingly absent from the islands much of the summer, which left us with a small sample size. In fact, for the month of August 2017, the SRKWs were nowhere to be found. This year’s longer field season produced much more data. There were 29 days with whales present around San Juan Island. We had tracking stations set up in three locations along the west side of San Juan Island: County Park, Hannah Heights, and Cattle Point, which allowed us to get close to continuous tracks along Haro Strait. We are excited to analyze the data, which should allow us to determine more about killer whale behavior in the presence of these slower ships.

This work felt profoundly important this year, in a season riddled with heartbreaking news about the endangered southern residents. J35’s calf died shortly after being born, and the mother mourned the loss of her offspring by pushing around the carcass for 17 days. J50, the youngest individual in the southern resident population, was found to be critically malnourished. NOAA launched the first attempt to supplement a southern resident killer whale’s diet with additional fish. Unfortunately she has not been seen since September 7 and is presumed dead. It is abundantly clear than additional conservation effort is needed, and our team worked hard to make this field season count, both in the field and on the Southern Resident Killer Whale Task Force.

This work wouldn’t have been possible without a super pod of a team. The Oceans Initiative team was led by Erin and Rob, and consisted of our employees Laurel Yruretagoyena, Natalie Mastick, and Laura Bogaard, as well as Toby Hall, Sarah Colosimo, Jess and Chris Newley, and Elizabeth Robinson, who provided additional field support.

Thank you, as always, for supporting our efforts to keep orca habitat clean, quiet, and full of salmon.

The critically endangered southern resident killer whale population now numbers 74 individuals. The ability of the population to recover is hindered by a perfect storm of threats—not enough salmon, too much noise, and toxic chemicals affecting calf survival—but lack of access to salmon is at the eye of that storm.

We need to recover Chinook salmon stocks throughout the whales’ range. 

We support all efforts to do so. We support dam removal, where this will get more salmon into the environment. We applaud the recent announcement to reduce salmon fishing quotas until the whales recovery, which will reduce our competition with the whales. While we wait for those measures to take effect, we need your help to give the whales a fighting chance to find as many of those salmon as possible in a noisy ocean.

We need to give the whales a quiet place to hunt for salmon

Our work has shown that killer whales spend 18-25% less time feeding on salmon when boats are around than when they are undisturbed. We have found that the southern resident killer whale population needs 662 big, fat Chinook salmon each day. We have found that mothers with calves need 43% more calories, more salmon, than adult females without calves.

A protected area can help the whales if we put it in the right place. 

We have found that killer whales are more vulnerable to disturbance when they are feeding than when they are travelling from A to B. They also need more salmon. We have identified areas that whales use preferentially for feeding. (One is called Salmon Bank. We have a feeling the whales knew this before people did.) We need to bring together all dedicated datasets we can use to identify areas where the whales are finding salmon, so we can prioritize those for protection. Protecting key feeding areas is essential to protecting the whales.

Please support our efforts to keep orca habitat clean, quiet, and full of fat, wild salmon.

PS Thanks to our team, especially Toby Hall, for the great footage, and to our friends at SeaLegacy for help editing this video.

Southern resident killer whales are in decline.  Our recent population viability analysis on southern resident killer whales predicted that, if threats remained constant, it should take several decades for the population to decline from 80 to 75 whales. In fact, that decline took only three years. We fear that the decline is accelerating, and we may be reaching a tipping point.

By studying killer whales from land, we can measure their responses to noise without adding the noise of a research boat to the equation. We use noninvasive techniques to measure swimming speeds, breathing rates, and other behavior. Our work on both northern and southern resident orca has shown us that the whales spend 18-25% less time feeding in the presence of boats than in their absence.

We recently joined an international, interdisciplinary study to understand the relative importance of the three main threats to recovery in the endangered killer whale population. The whales are facing a perfect storm of threats–not enough salmon, too much noise, and too many toxic chemicals in their bodies–but lack of prey is at the eye of the storm. This research shows it will take 30% more big, fatty, Chinook salmon than we’ve seen on average over the last 40 years for the population to reach our recovery goals. That will take time, but we have to start now. Meanwhile, reducing noise and disturbance can help make it a little bit easier for whales to find the salmon we have now. In the coming months, we will be revisiting our study on identifying critical foraging areas in the Salish Sea and strengthening their protection.

Teamwork

One of the things we admire most about orca or killer whale cultures is their commitment to teamwork. They work together to find food, coordinate travel, and thrive in a cold, dark environment where prey are easier to find using sound than light. These whales serve as a great template for people working together to tackle some of the world’s most pressing environmental problems, including unsustainable fishing, climate change, and ocean noise. These are challenging times.

As we enter World Oceans Week, we are inspired by the team at Sea Legacy, including the amazing conservation photographers, Cristina Mittermeier and Paul Nicklen. In words and in deed, they show that we can accomplish more #together than we can as separate voices. Taking a cue from Paul and Cristina, we’d like to offer the Oceans Initiative team three ways to help during Oceans Week.

  1. Spread the word. We do “use-inspired science” to guide effective conservation of marine wildlife. By definition, you are a key part of the research questions we ask, and what we do with the information we produce. We can’t do this without you. We’d love to hear from you. Please comment on this blog, or share it with your friends. Sign up for our newsletter. We never share lists, and we won’t fill up your inbox. Encourage your friends to like us on Facebook, and actually click the “follow” button to see what we post. We’d love to hear from you on Facebook, because the platform lends itself to back and forth conversations. Our Twitter feed is interactive, and light, but focuses on emerging science on marine conservation and solutions. We have a large and growing audience on Instagram, and we’d love to see you there. These sound like trivial things, but they matter. Many funders use social media metrics as an indicator of a nonprofit’s reach. Please help us spread the word about our work.
  2. Donate frequent flyer miles. Aeroplan, Air Canada‘s frequent flyer program, is matching all donations of Aeroplan miles 1:1, up to 500,000 miles, this week. Your donated miles help in many ways. The flights get our team to the field, bring top scientists and aspiring young biologists to join us, let us bring our skills to other countries to help build capacity in lower-income countries, and ultimately, to take the information to the meetings where important conservation decisions are made. Aeroplan even offsets the carbon footprint for every flight we redeem through this special program.
  3. Invest in our work. As much as we try to do more with less and be good stewards of charitable dollars, it still takes money to do the conservation work we do. Every dollar made to our partner charity in Canada enters us in a draw to win $10,000 from CanadaHelps. Every dollar is directed to the dolphin conservation project in British Columbia. American taxpayers can receive a tax receipt for any donation made through our website.

Thank you so much for your help. We are starting to see some real-world conservation successes emerging from our work on ocean noise and marine mammal bycatch in fisheries. Thank you for allowing us to do that work.
