Changing Ocean Temperatures and Marine Ecosystems
The warming of ocean temperatures has had a significant impact on marine species, ecosystems, and the industries that rely on them. Warming ocean temperatures have been observed for several decades, leading to a range of ecological changes.
One of the consequences of warming ocean temperatures is declining oxygen levels, which can have detrimental effects on marine life. As sea surface temperatures increase, the dissolved oxygen concentration in the water decreases, making it harder for fishes and invertebrates to survive. Reduced oxygen levels can lead to the expansion of dead zones, areas in the ocean where oxygen levels are so low that marine life cannot thrive.
Furthermore, warming ocean temperatures also result in reduced habitat availability for marine species. As water temperatures increase, some species may shift their distribution to find suitable environments, while others may struggle to survive in their current habitats. This can lead to changes in species composition and ecosystem dynamics, impacting the overall biodiversity and productivity of marine ecosystems.
An important event that highlights the impact of warming ocean temperatures is the 2015 ‘warm blob’ phenomenon. This event, characterized by unusually high sea surface temperatures in the northeastern Pacific Ocean, had wide-ranging effects on marine ecosystems. The ‘warm blob’ contributed to the proliferation of harmful algae blooms, affecting the health of marine organisms and disrupting food chains.
The 2015 ‘warm blob’ event could be linked to long-term climate warming. Sightings of warm water species and unusual biological events during this period indicate potential species range shifts and ecosystem responses.
The impacts of changing ocean temperatures on marine ecosystems are of great concern due to their implications for the sustainability of important marine resources and the communities that depend on them. It is crucial to understand and effectively manage these changes to protect and preserve the health and resilience of marine ecosystems in the face of ongoing and future climate change.
Impacts on Fisheries and Aquaculture
The warming trend in sea surface temperatures has had significant impacts on fisheries catches and landed values in British Columbia (BC) since the 1990s. One specific example is the decline of Fraser River sockeye salmon, a vital species for both commercial and recreational fishing in the region.
The Fraser River sockeye salmon is an iconic species that supports various industries and plays a crucial role in the culture and traditions of local First Nations communities. However, the warming temperatures have led to diminished returns of this species, affecting the livelihoods of fishermen and the overall ecosystem.
Furthermore, ocean acidification, particularly along BC’s south coast, is becoming an increasingly concerning issue. Acidification is the result of increased carbon dioxide (CO2) absorption by the ocean, leading to a decrease in pH levels. This has serious consequences for calcifying organisms, such as mollusks, bivalves, sea urchins, and sea cucumbers, which have shells or skeletons made of calcium carbonate and are crucial for both wild and farmed marine resources.
The acidification of the ocean threatens the survival and growth of these organisms, disrupting the delicate balance of BC’s aquaculture industry and traditional food resources.
To better understand the severity of the issue, let’s take a closer look at the specific impacts of warming sea temperatures and ocean acidification:
